Module 3 Review (3.1-3.5) Name: ________________________________

1. Write a definition and how to locate the feature on a graph. a. Function b. Domain c. Range d. Increasing e. Decreasing f. Constant g. Maximum h. Minimum i. Discrete j. Continuous k. Discontinuous

2. Graph lines given a start value and a common difference (slope)

3. Write functions given a story and evaluate amounts based on context.

a. Ms. Plant has 4 Reese’s Cups in her desk. Each week on Friday, her favorite student brings her 3 more Reese’s Cups.

i. Write a function called r(x) to represent the amount of Reese’s Cups Ms. Plant will have at the start of any week. (Assume she’s saving them up to pig out one day!)

ii. Evaluate r(6)

iii. What does r(6) represent in the context?

b. Coach Capel has 100 stickers. Each day he gives out 9 stickers (3 to each class period) to his

students who behave and participate in class. i. Write a function called s(x) to represent the amount of stickers Coach Capel will

have at the start of any day. (Assume he does not buy additional stickers)

ii. Evaluate s(8)

iii. What does s(8) represent in the context?

4. Understand how to find an intersection on a graph and how to evaluate and calculate specific values.

Where does 𝑚(𝑥) = 𝑛(𝑥)? Where does 𝑎(𝑥) = 𝑏(𝑥)?

What is 𝑚(0) + 𝑛(0)? What is 𝑎(−2) + 𝑏(−2)?

What is 𝑚(3) − 𝑛(3)? What is 𝑎(0) − 𝑏(0)?

5. Identify ALL features of functions using interval notation. (intercepts, domain, range, maximum, minimum, increasing, decreasing, constant)
