d. 6x + 25

Answer 1

(g,f)(x) = g(f(x)) ?

Answer 2

TYPO::: c. x-5/6

Answer 3

These are inverses of each other so the answer is A.

Answer 4

yea.. i got messed up on this one

Answer 5

g(f(x)) means plug f(x) into g

Answer 6

so you see all the x's in g?
change those to ( x- 5/6)

Answer 7

6(x - 5/6) + 5 = g(f(x)) ... i think lol

(6x - 5) + 5 = g (f(x))
6x = g(f(x))

Answer 8
