First find h[j(x)]

Answer 5

okay, and how would I do that?

Answer 6

Do you know the expression for j(x)?

Answer 7

yesh, −2x or in this case -2*2

Answer 8

-2x is the expression for j(x) which means h[j(x)] = h[-2x]

Answer 9

-4*5

Answer 10

Jumping ahead isn't a very good idea.

Answer 11

okay..

Answer 12

The next step is to take the expression for h(x) and replace x with -2x:

h[j(x)] = h[-2x]
= 3[-2x] - 1
