Answer:
x = - , x = 2
Step-by-step explanation:
To find h(g(x)) substitute x = g(x) into h(x) , that is
h(g(x))
= h(x + 1)
= (x + 1)²
= x² + 2x + 1
For h(g(x)) = 3x² + x - 5 , then
3x² + x - 5 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides
2x² - x - 6 = 0 ← in standard form
(2x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = -
x - 2 = 0 ⇒ x = 2

Answer:
1) 14
2) 18
3) -6
4) 2
5) 80
Step-by-step explanation:
1) (2)(2)+4-(3)(-2) = 14
2) (3)(2)(4)-3(2) = 18
3) (6)(4)/(2)(-2) = -6
4) [(2)(4)-(2)(2)] +(-2) = 2
5) (-5)(2)(4)(-2) = 80
