Question

HELP ME PLEASE
For f(x) = 9x-6 and g(x)=(1/9)(x+6), find f(g(x)) and g(f(x)). then determine whether f(g(x))=g(f(x))

Answer 1

For f(g(x))...plug g(x) into f(x). So you plug (1/9)(x+6) into every x you see in f(x).
Then do it for g(f(x)).
Then simplify to see if they equal.
Does that make sense...?

Answer 2

I got 9((1/9)(x-6) for f(g(x))
and (1/9)(9x+6)-6 for g(f(x)) should I simply it more?
