Question

PLEASE HELP.

Let g (x) = 2x, and h(x)=x^2 -1

1. g(-1)
2. g(x)*h(x)
3. h(2) - g(-3)
4. h (3)
5. h(h(3))
6. g(-2)*h(-2)

Answer 1

1 g(-1) = 2(-1) = -2

2 g(x)*h(x) = 2x(x^2 -1) = 2x^3 - 2x

3 h(2) - g(-3) = (2^2 -1) - 2(-3) = 7

4 h(3) = 3^2 - 1 = 8

5 h(h(3)) = h(8) = 8^2 - 1 = 63

6 g(-2)*h(-2) = 2(-2)(-2^2 - 1) = -20
