Thread: Inverses of (f o g)(x) (g o f)(x)

Hello new to this forum hopefully I ask this properly.... so my problem is this
Let f(x) = e^x and g(x) = ln x
Compute (f o g)(x) and (g o f)(x) and last are f and g inverses explain?

Thank you so much for your time!

Review your notes and textbook.
Once that is done it will be clear how to answer these:

Thank you I was just afraid there might have been some sort of trick.... cuz usually when something comes out that easy its because you have done something wrong or missed a step.
