Can anyone with problems 6 and 8 those are the only ones i cannot figure out

Step-by-step explanation:

We have the following functions:

and

First we find

To find we must add the function f(x) with the function g(x)

Now we find

To find we must subtract the function f(x) with the function g(x)

step-by-step explanation:

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.
