Question

If h(x)=(fog)(x) and h(x)= the sqrt of (x+5); find g(x) if f (x)= the sqrt of (x+2).

Answer 1

what does f composed of g look like if f composed of x is: sqrt(x+2)?

Answer 2

since h composed of x is: sqrt(x+5)

and since h composed of x is equivalent to f composed of g ... we can solve for g
