I have to find the composition of functions! I did 16 problems already with no problem but can't figure this one out.
g(x)=(2x)^1/2 and f(x)=x^2+1. Then find (Fog)(x)=F(g(x))

Step 1. Substitute g(x)=2x^1/2 into f(x) as follows

Step 2.

Step 3. ANSWER: Fog(x)=F(g(x))=2x+1

I hope the above steps were helpful.
