Question

Perform the requested operation or operations.

f(x) = (x-3)/(8) .; g(x) = 8x + 3, find g(f(x)).

Answer Choice:

g(f(x)) = x

g(f(x)) = x - three divided by eight.

g(f(x)) = 8x + 21

g(f(x)) = x + 6

Answer 1

Have you considered substituting f(x) into g(x) and working the remaining algebra?

Answer 2

Well, I just keep getting x, as my answer. However I am not sure if that is correct.

Answer 3

Did you do it incorrectly on purpose? If not, why do you doubt? Show your work and I can verify.

Answer 4

Well, I believe that g (f (x)) = x, the problem is that I am not sure, that is why I need someone to verify.

Answer 5

Did you yet show your work? I' can't show it for you.

Answer 6

It's fine, I was correct. Thank You

Answer 7

Note: If functions are inverses of each other, that is the expected result. f(g(x)) = g(f(x)) = x

Answer 8

Oh, I did not know that. Thank You !
