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

Try first column:-
5 - 2 = 1/4(x + 8)
3 = 1/4x + 2
1/4x = 1
x = 4
B is the correct choice
X - 3y = -6
3y = -x - 6
y = 1/3x + 2
y-intercept is 2
