Four Representations of Functions

5. Warm Up
Video!

6. Think, Pair, Share
What do you know about graphing linear equations, after watching the video?

7. The Great Barrier Reef, Queensland, Australia

8. Learning Intention/Success Criteria
LI: We are learning the different ways to represent a function
SC: I know how to… 1. identify the four representations of functions 2. move between the four representation of functions 3. graph and identify ordered pairs 4. evaluate expressions and equations 5. evaluate functions from tables, graphs, equations, and context clues

9. Today’s Vocabulary Linear Function:
The equation of a function representing a straight line
Slope-Intercept Form:
The equation of a line in a the form: f(x) = mx + b
y-intercept
slope

10. Today’s Vocabulary Slope: Indicates the steepness of a line
Indicates if the line is tilted uphill or downhill
Represented by the letter “m”
Y-Intercept:
The point at which the graph intersects the y-axis
Represented by the letter “b”

11. Today’s Vocabulary Symbolic Representation:
A function represented as an equation
Visual Representation:
A function represented as an graph
Numeric Representation
A function represented as a table or set of ordered pairs

12. Today’s Vocabulary Verbal Representation:
A function represented in words, often depicting a real world situation

13. Example 1: Using the given verbal representation, find the symbolic, visual, and numeric representations
At the Makai parking garage, it costs $5 to bring your car into the garage plus $2 for every hour the car is parked.
Slope:
Y-Intercept:
Equation: 2 5
C(h) = 2h + 5

16. Group Work Directions
Work with your Country to come up with the answers for your assigned page.
You will be presenting your findings to the class upon finishing with your group
Whatever is not presented in class will be assigned for homework.

23. Passport Stamp
Grade yourself with a passport stamp at the Great Barrier Reef. How deep are you diving to see the animals? Represent your learning with how deep you will be diving, between 0 and -100 feet. The smaller the number, the deeper you are, which means understand it more 
