Question

Use the graph below to fill in the blank with the correct number:

f(1) = _______

Answer 1

f(1)=-2.

Explanation:

We are given a graph with four points on the graph with coordinates as following:

(-3,0)

(-2,2)

(0,1) and

(1,-2).

We need to find the value of function f(x) at x=1 that is f(1) =?

That means we need to find the y-coordinate of the point, where x coordinate is at 1.

We can see tat fourth point on the graph (1,-2) has x-coordinate at 1 and y-coordinate at -2.

Therefore, f(1)=-2.
