3 PBIS and Classroom Expectations
Parkside High School PBIS and Classroom Expectations

4 #RAMFAM OBJECTIVES All students will use skills to interact effectively with diverse populations All students will help create a climate that is welcoming, encouraging, and supportive All students will learn in a positive learning environment

5 What is PBIS? systems of support that include:
positive strategies that define and teach appropriate student behaviors programs that support students to create a positive school environment implemented in areas including: all classrooms non-classroom settings (such as hallways, cafeteria and restrooms)

6 PARKSIDE #RAMFAM # - To bring immediate attention, unite a group with a common theme Being a part of Parkside’s Legacy Respectful – Having high regard for self and others while appreciating differences and commonalities Being polite and mannerly toward others will create a positive environment Attendance – To be present and devoted Being here and on time prepares you to go elsewhere Management – To take charge and handle until progress is made or accomplished Being able to devote appropriate time to academics and extracurriculars

7 PARKSIDE #RAMFAM Focused – The act of directing one’s attention or efforts. Be focused on your potential Achievement – The act of reaching an objective, accomplishment, and completing something successfully Being able to say “I did it!” Meaningful – To find purpose, value, and significance Being able to make your time here count

Challenges (in school or personal) Goal for this year

12 Creating a SMART Goal Specific: the goal should be well defined so that you know exactly the intended outcome for the goal. Measurable: the goal should have a way to measure progress to provide evidence of it being met or not met. Achievable: the goal should challenge you, so that it is worthwhile to work on, but that it is also a realistic task for you to accomplish. Rewarding/Relevant: the goal should be important to you, your work and focus on results. Time-bound: the goal should always indicate a timed deadline for its outcome.

In the sequence 10, 40, 70, 100, …. The constant difference between the terms is 30 The first term of the sequence is 10 The explicit formula for this sequence would be: an = ( n - 1) which simplifies to: an = n **I substituted in 10 for the first term and 30 for the constant difference and distributed**

98 Objectives Graph and recognize inverses of relations and functions.
Find inverses of functions.

99 Vocabulary inverse relation inverse function

100 You have seen the word inverse used in various ways.
The additive inverse of 3 is –3. The multiplicative inverse of 5 is

101 You can also find and apply inverses to relations and functions
You can also find and apply inverses to relations and functions. To graph the inverse relation, you can reflect each point across the line y = x. This is equivalent to switching the x- and y-values in each ordered pair of the relation. A relation is a set of ordered pairs. A function is a relation in which each x-value has, at most, one y-value paired with it. Remember!

102 Example 1: Graphing Inverse Relations
Graph the relation and connect the points. Then graph the inverse. Identify the domain and range of each relation. x 1 5 8 y 2 6 9 Graph each ordered pair and connect them. Switch the x- and y-values in each ordered pair. x 2 5 6 9 y 1 8

103 Example 1 Continued Reflect each point across y = x, and connect them. Make sure the points match those in the table. Domain:{x|0 ≤ x ≤ 8} Range :{y|2 ≤ y ≤ 9} Domain:{x|2 ≤ x ≤ 9} Range :{y|0 ≤ y ≤ 8}

104 1 3 4 5 6 2 • • • • • Check It Out! Example 1
Graph the relation and connect the points. Then graph the inverse. Identify the domain and range of each relation. x 1 3 4 5 6 y 2 Graph each ordered pair and connect them. Switch the x- and y-values in each ordered pair. x 1 2 3 5 y 4 6

105 Check It Out! Example 1 Continued
Reflect each point across y = x, and connect them. Make sure the points match those in the table. Domain:{x| 1 ≤ x ≤ 6} Range :{y| 0 ≤ y ≤ 5} Domain:{x| 0 ≤ x ≤5} Range :{y| 1 ≤ y ≤ 6}

106 When the relation is also a function, you can write the inverse of the function f(x) as f–1(x). This notation does not indicate a reciprocal. Functions that undo each other are inverse functions. To find the inverse function, use the inverse operation. In the example above, 6 is added to x in f(x), so 6 is subtracted to find f–1(x).

107 Example 2: Writing Inverses of by Using Inverse Functions
Use inverse operations to write the inverse of f(x) = x – if possible. 1 2 f(x) = x – 1 2 is subtracted from the variable, x. 1 2 1 2 f–1(x) = x + Add to x to write the inverse. 1 2

108 Check Use the input x = 1 in f(x).
Example 2 Continued Check Use the input x = 1 in f(x). f(x) = x – 1 2 f(1) = 1 – 1 2 Substitute 1 for x. = 1 2 Substitute the result into f–1(x) 1 2 f–1(x) = x + 1 2 f–1( ) = + 1 2 Substitute for x. = 1 The inverse function does undo the original function.

109 Use inverse operations to write the inverse of f(x) = . x 3
Check It Out! Example 2a Use inverse operations to write the inverse of f(x) = . x 3 x 3 f(x) = The variable x, is divided by 3. f–1(x) = 3x Multiply by 3 to write the inverse.

110 Check It Out! Example 2a Continued
Check Use the input x = 1 in f(x). x 3 f(x) = 1 3 f(1) = Substitute 1 for x. = 1 3 Substitute the result into f–1(x) f–1(x) = 3x f–1( ) = 3( ) 1 3 1 3 Substitute for x. = 1 The inverse function does undo the original function.

111 Use inverse operations to write the inverse of f(x) = x + .
Check It Out! Example 2b Use inverse operations to write the inverse of f(x) = x 2 3 f(x) = x + 2 3 is added to the variable, x. 2 3 2 3 f–1(x) = x – Subtract from x to write the inverse. 2 3

112 Check It Out! Example 2b Continued
Check Use the input x = 1 in f(x). f(x) = x + 2 3 f(1) = 1 + 2 3 Substitute 1 for x. = 5 3 Substitute the result into f–1(x) 2 3 f–1(x) = x – 2 3 f–1( ) = – 5 5 3 Substitute for x. = 1 The inverse function does undo the original function.

113 Undo operations in the opposite order of the order of operations.
The reverse order of operations: Addition or Subtraction Multiplication or Division Exponents Parentheses Helpful Hint

114 Example 3: Writing Inverses of Multi-Step Functions
Use inverse operations to write the inverse of f(x) = 3(x – 7). The variable x is subtracted by 7, then is multiplied by 3. f(x) = 3(x – 7) 1 3 f–1(x) = x + 7 First, undo the multiplication by dividing by 3. Then, undo the subtraction by adding 7. Check Use a sample input. 1 3 f–1(6) = (6) + 7= 2 + 7= 9 f(9) = 3(9 – 7) = 3(2) = 6

115 Use inverse operations to write the inverse of f(x) = 5x – 7.
Check It Out! Example 3 Use inverse operations to write the inverse of f(x) = 5x – 7. The variable x is multiplied by 5, then 7 is subtracted. f(x) = 5x – 7. f–1(x) = x + 7 5 First, undo the subtraction by adding by 7. Then, undo the multiplication by dividing by 5. Check Use a sample input. f–1(3) = = = 2 f(2) = 5(2) – 7 = 3 10 5 3 + 7

116 You can also find the inverse function by writing the original function with x and y switched and then solving for y.

117 Example 4: Writing and Graphing Inverse Functions
Graph f(x) = – x – 5. Then write the inverse and graph. 1 2 1 2 y = – x – 5 Set y = f(x) and graph f. 1 2 x = – y – 5 Switch x and y. x + 5 = – y 1 2 Solve for y. –2x – 10 = y y = –2(x + 5) Write in y = format.

118 Example 4 Continued f–1(x) = –2(x + 5) Set y = f(x). f–1(x) = –2x – 10
Simplify. Then graph f–1. f –1 f

119 Graph f(x) = x + 2. Then write the inverse and graph.
Check It Out! Example 4 Graph f(x) = x + 2. Then write the inverse and graph. 2 3 2 3 y = x + 2 Set y = f(x) and graph f. 2 3 x = y + 2 Switch x and y. x – 2 = y 2 3 Solve for y. 3x – 6 = 2y Write in y = format. x – 3 = y 3 2

120 Set y = f(x). Then graph f–1.
Check It Out! Example 4 f–1(x) = x – 3 3 2 Set y = f(x). Then graph f–1. f f –1

121 Anytime you need to undo an operation or work backward from a result to the original input, you can apply inverse functions. In a real-world situation, don’t switch the variables, because they are named for specific quantities. Remember!
