R drive > Key > Week 15 > Friday > 1.5_8.1 PowerPoint File > Save As > P drive > Math > Week 15 > 1.5_8.1 PowerPoint

3. Vocabulary
Function – A relation in which each element of the domain is paired with exactly one element in the range.
Function Rule – The operation performed on the input of a function
Function Table – A table organizing the input, rule, and output of a function.

4. Vocabulary Input – What you put into the function; the x value
Output – What comes out of the function; the y value

5. Example 1 Make a Function Table

6. Example 2 Make a Function Table

7. Example 3 Make a Function Table
Make a function table for four different input values and write an algebraic expression for the rule. Then state the domain and range of the function. RULE: Double a number and subtract one

8. Notes
Functions are often written as equations with two variables – one to represent the input and one to represent the output

9. Example 4 Use Multiple Representations

10. Example 5 Use Multiple Representations
An assembly line produces 30 boxes per hours.
Write an equation to find the amount of boxes it can produce for any number of hours
Make a function table for 5, 10, 15, and 20 hours of production. Then graph the ordered pairs.
