Question

At what values of x, does f(x)=0? mark all that apply

a.-4
b.-2
c.0
d.1
e.3
f.8

Answer 1

Option b , d and e are correct.

values of x is -2, 1 and 3 for which f(x) = 0.

Explanation:

x-intercepts is the value of x for which f(x) = 0 i.e, where the graph of the function crosses the x-axis and is found by solving the equation f(x) = 0.

we have to find the values of x where f(x) =0

From the given graph you can see that the graph crosses the x-axis at three points (x, f(x))

i.e, (-2 ,0) , (1, 0) and (3, 0)

therefore, the values of x for which f(x) = 0 is, -2 , 1 and 3

Answer 2

The x-intercepts are shown on the graph to be at x = -2, 1, 3, corresponding to
.. selections B, D, E.
