Question

!!!!!!!!!!!!Help!!!!!!!!!!!!!!!!!!

Answer 1

3

Explanation:

f(x) = 0 means that y =0, which is basically the x-intercept. If you look at the graph, you'll se that the x-intercept is (3,0). This means that the value of x for which f(x)=0 is 3.

Answer 2

f(x) = 0 at x=3

Explanation:

f(x) = 0 is where the y value is 0

This is where it crosses the x axis

It crosses the x axis at x=3

f(x) = 0 at x=3
