Question

The graph of the function f(x) is shown below.

What is x when f(x)=0?

-1.8

-1.2
0
5

Answer 1

A.
`-1.8`

Explanation:

We have been graph of a function. We are asked to find the value of x, when
`f(x)=0`.

We know that
`f(x)=0` stands for x-intercept.
`f(x)` stands for value of y. We know that y is zero on x-axis.

Upon looking at our given graph, we can see that our function has only one x-intercept that is at point
`(-1.8,0)`.

This means that
`f(-1.8)=0`, therefore, the value of x is
`-1.8` and option A is the correct choice.

Answer 2

a -1.8

Explanation:

f(x)=y=0

when y = 0, x=-1.8
