Step-by-step explanation:
If x + 7 is a factor of f(x), then f(-7) = 0.
f(-7) = (-7)³ − 3(-7)² + 2(-7) − 8
f(-7) = -343 − 147 − 14 − 8
f(-7) = -512
x + 7 is not a factor of f(x).

x=c-y. / x=py/q
y=c-x. / y=xq/p

171
First you plug -4 into the g(x) equation
g(-4)= 1-3(-4)
Use pemdas
g(-4)= 1+12
g(-4)= 13
Next you plug 13 into the f(x) equation
f(13)= 13^2 + 2
First you do 13^2=169
Add 2 and you get 171
