Asked by Anna
Given:
f(x)=2+x
g(x)=sqrt(x-7)
h(x)=2x^2-5
Determine: g(h(x))
This is what I've got so far:
f(x)=2+x
g(x)=sqrt(x-7)
h(x)=2x^2-5
g[h(x)]=sqrt(h(x)-7)
And I don't know if that's right or not >_<
Please help!

and continue...
g[h(x)]=sqrt(2x^2-5-7)
= sqrt(2x^2-12)
g[h(x)]=sqrt(2x^2-5-7)
= sqrt(2x^2-12)
