Answer 4

x for F(x) = g(x).

Answer 5

That's the only part I actually understand

Answer 6

f(g(x)) = 3(x^2 - 2x - 2) - 1

Simplify that

Answer 7

do we distribute the -1 on the right side to 3x^2-6x-6?

Answer 8

No, why would you?

Answer 9

F(x) must stay the same except for the x which will be replace by g(x) as shown by Hero.

Answer 10

I was just making sure

Answer 11

You just combine like terms and simplify. You can't distribute that -1

Answer 12

3x^2-6x-7

Thanks everyone!
