Question

The function f(x) is shown on the graph. If f(x) = 0, what is x?

A: 0 only
B: -6 only
C: -2, 1, or 3 only
D: -6, -2, 1, or 3 only

​

Answer 1

Answer:

C

Step-by-step explanation:

note y = f(x) = 0

y = 0 is the x- axis

We are looking for values of x on the x- axis where the graph crosses/touches

This occurs at

x = - 2, x = 1, x = 3 → C
