Answer:
-2x² + 15
Step-by-step explanation:
Step 1: Add like terms
4x² - 6x² = -2x²
-10x + 10x = 0
3 + 12 = 15
Step 2: Rewrite
-2x² + 15

Answer:
a). -6x³ - 12x² b). -12 c). 12
Step-by-step explanation:
a). (g x f)(x) can also equal f(g(x))
= f (2x +4)
= -3x² (2x+4)
= -6x³ - 12x²
b). f(g(-1))
g(-1) = 2(-1) + 4
= -2 + 4
= 2
f(2) = -3x²
= -3(2)²
= -12
c). g(h(3))
h(3) = 3x-1/2
= 3(3) - 1 / 2
= 4
g(4) = 2x + 4
= 2(4) + 4
= 12
