Answer:
f(x^3-8)=x^6-19x^3+90
Step-by-step explanation:
Answer: Choice B
The slope is rise/run = 2/3 meaning we go up 2 and over to the right 3. For instance, moving from (0,0) to (3,2) has us move up 2 and over to the right 3.
Alternatively you can use the slope formula m = (y2-y1)/(x2-x1) to get the same result of 2/3.

Answer: -10</h3>
=================================================
Work Shown:
First we need to evaluate f(3)
f(x) = -x^2 + 2x
f(x) = -(x)^2 + 2(x)
f(3) = -(3)^2 + 2(3) ... replace every x with 3; apply PEMDAS to simplify
f(3) = -9 + 6
f(3) = -3
Then we subtract 7 from both sides
f(3) - 7 = -3 - 7
f(3) - 7 = -10
