Use the graph to find the indicated value of the function.

Answer 1

If a pair related to the function is graphed

Then

• (x,y) be a pair

So

f(x)=y

• x is domain
• y is range

Her e

• f(-2)

Find the point

• (-2,2)

So

f(-2)=2

Answer 2

f(-2) means the x value is -2 and you need to find the y value at that point.

At x = -2 the line crosses the y axis at y = 2

f(-2) = 2
