MINI LESSON

Comparing Functions

Functions can be compared using graphs, equations, and tables.

A y-intercept is the value of a function when \(x=0\).

To compare rates of change or intercepts, use the representation that is given and evaluate carefully.

Question 1

Which graph below represents a function that is always decreasing over the entire interval \(-3 < x < 3\)?

Question 2

Three functions are given below. Which functions have the same y-intercept?
