Question

At what values of x, does f(x) = 0?

A. 4
B. 0
C. 2
D. 4.2
E. -8
F. -1​

Answer 1

-1, 2, 4

Explanation:

f(x) is the function's value at any given x. In other words, it's your function's y coordinate. You're looking for where the y coordinate is zero - so, in other words, the x intercepts. Luckily for you, all the x-intercepts here are clearly marked and they were kind enough to give you the coordinates.
