Which input value produces the same output value for the two functions on the graph?

x = −3
x = −2
x = −1
x = 3

x = -2

The line represents the output value (y) for a given input value (x). Where the lines cross, the output values are equal. These lines cross at x=-2.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
