Hey I need some help with functions, I have it most of the way I just wanted to know what I have to do after this.

Question

anonymous · Answer

Let f(x) = x^2 + x + 2 and g(x) = 2x^2 + 5. Find f(g(x)). Show each step of your work.

anonymous · Answer

all I do is substitute g(x) everywhere there is an x in the equation right?

f(2x^2+5)=(2x^2+5)^2+2x^2+5)+2

then simplify to 

f(sx^2+5)=4x^4+25)+(2x^2+5)+2

anonymous · Answer

no I messed up on the beginning; then simplify to 

f(2x^2+5)=(4x^4+25)+2x^2+5)+2
