# Math Help - combination of functions

1. ## combination of functions

Let f(x) = kx^(2) + B
and g(x) = C^(2x)
and h(x) = kx^(2)C^(2x) + BC^(2x) + C^(2x)

Suppose f(3) = 7 and g(3) = 5
Evaluate h(3)

I thought I was on the right track, but not coming up with the right answer :/

Well it appears that $h(x)=\left[f(x)+1\right]g(x)$.
Is that what you are using?
