Answer:
f(4) = -6, g(-3) = 36
Step-by-step explanation:
To find f(#) or g(#), plug the number into each x of the equation.
f(x) = -2x + 2
f(4) = -2(4) + 2
Simplify the parentheses by multiplying.
f(4) = -8 + 2
Add.
f(4) = -6
g(x) = 3x² - 3x
g(-3) = 3(-3)² - 3(-3)
Simplify the exponent first.
g(-3) = 3(9) - 3(-3)
Simplify the parentheses by multiplying.
g(-3) = 27 + 9
Add.
g(-3) = 36
