Answer 1

F(x) = 2 / (x-1) ; G(x) = 4x - 1
(F o G)(x) = F(G(x)) = 2 / ( (4x-1) - 1) = 2 / (4x-2) = 2/{2(2x-1)) = 1/(2x-1)

Answer 2

thank you. do you mind helping me with another one?

Answer 4

go ahead and post the question here.

Answer 5

Same method as before.
F(x) = 3 / (x - 1) G(x) = 2x - 7
(G o F)(x) = G(F(x)) = 2{ 3/(x-1) } - 7 = 6/(x-1) - 7

Answer 6

I got the same answer. It says that it is incorrect, but thank you.
