I assume you mean

h(x) = [√(x

^{2}+ 9)]^{3}There is more than one way to get h(x) from composing 2 functions. Here is one:

g(x) = √(x

^{2}+ 9)Let f(x) = x

^{3}f(g(x)) = [√(x

^{2}+ 9)]^{3}Here is another:

You can express h(x) as

h(x) = (x

^{2}+ 9)^{3/2}= √[(x^{2}+ 9)^{3}]g(x) = (x

^{2}+ 9)^{3}f(x) = √x

f(g(x)) = √[(x

^{2}+ 9)^{3}]
