Question 160480: f(x)=x^3. g(x)=(sq. root of)x. h(x)=x-4. and j(x)=2x. If k(x)=(sq. root of x^3-4), Express k(x) as a composite of three of the four functions listed. Please explain how you arrived at your solution! I'm begging for help!!!

You can put this solution on YOUR website!
start with f(x) __ that's your x^3

h(x) subtracts 4 __ so h(f(x))=x^3-4

last is g(x) __ it takes sqrt __ g(h(f(x)))=sqrt(x^3-4)

k(x)=g(h(f(x)))
