    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?
