Thread: Find Functions (FoG)

Find functions f and g so that (fog)(x)=2/(6x+1)

(6x+1) is all square rooted. I tried to enter alt251 for the square root symbol, but it didn't work.

I am not sure what the question is asking and how to start the problem...

You can learn to use LaTex
The code [tex]f \circ g(x) = \frac{2}{{\sqrt {6x + 1} }}[/tex] gives nice output: .

Let and .

what are the steps to get there?
I understand (fog)(x) is f(g(x)). I can't find a similar example.

Actually there are no steps.
It is a matter of understanding how functions work.
It is a matter of practice.
