Sorry. I posted my last question in the wrong section.. This is moree appropriate.

I understand functions for the most part, but I feel as if I'm overthinking this.

find g(f(x)), if defined..

f(x) = 2x-5

g(x) =5..

The answer says "5" but I don't understand why.

I can't input f into g .. the work shows

g(2x-5) = 5

I'm just looking for an explanation please

I'm going to try to delete the other thread now.
