Question

What is the value of the function at x=−2?

y=−4

y = 0

y = 2

y = 3

Answer 1

Option D.

Explanation:

If the graph of a function f(x) passes through the point (a,b), then the value of the function f(x) is b at x=a.

`f(a)=b`

`y=b`

The graph of a function is given.

We need to find the value of function at x=-2.

From the given graph it is clear that the graph is passes through the point (-2,3).

It means the value of function is 3 at x=-2.

`y=3`

Therefore, the correct option is D.

Answer 2

y = 3

find -2 on the x plane, and match the point, then get your y

hope this helps
