Question

What is the value of f(−1) when f(x)=2x+2 ?

f(−1)=


What is the value of the function at x=−2? The graph goes with this question.

y=−2

y = 0

y = 2

y = 3

Answer 1

0; 2

Explanation:

Function:

f(x)=2x+2

f(-1) = 2(-1) + 2 = -2 + 2 = 0

f(-1) = 0

Graph:

Look at the point on the graph that has x = -2. The point is (-2, 2), so y = 2.

Answer 2

the answer would be y=0
