• Linear

• Quadratic

• None of the Above

For the function ƒ(x) = 3 — 1.2x, find ƒ(−2), ƒ(2), ƒ (6), and ƒ (8).

The band is holding a car wash to raise money for its spring trip. The function f(x) = 3x - 10 models the money earned from the band car wash, with x representing the number of cars washed. Evaluate and interpret the solution for 4 cars.

The band earns ___ after washing 4 cars.

Callie and her friend Elena are reading through different novels they checked out from their school library last Tuesday. Callie's progress through her novel can be modeled by the function p(d) = −25d + 318, where p(d) represents the number of pages remaining to be read and d is the number of days since receiving the book. Elena's progress through her novel is modeled by the graph below.

Part A. Which student's novel has more pages to read?

Part B. Assuming they both continue to read at a constant rate, which student will complete their novel first?

Type the word "and" between each name

  B. Callie

• A. Elena

  B. Elena

• A. Callie

Two linear functions, f(x) and g(x), are represented below. Compare the functions by stating which has a greater y-intercept, x-intercept and rate of change.

f(x) = 4x - 3

• y-Int: f(x)

  x-Int: f(x)

  rate of change: g(x)

• y-Int: g(x)

  x-Int: f(x)

  rate of change: g(x)

• y-Int: f(x)

  x-Int: f(x)

  rate of change: f(x)

• y-Int: g(x)

  x-Int: g(x)

  rate of change: f(x)

The fee for a service call from a plumber can be modeled with the function C(h) = 75 + 20h, where C is the total cost of the service call and h is the number of hours the plumber spends working on the problem.
