Write the following as a composition of three non-identity functions

Question

(h ∘ g ∘ f)(x) = F(x) = square root of 2x+1

(f(x), g(x), h(x)) =

Answer 1

(h ∘ g ∘ f)(x) = F(x) = square root of 2x+1

(f(x), g(x), h(x)) =

(f(x), g(x), h(x)) =(2x,x+1,√x)\

as, since

f(x)=2x

g(f(x))=2x+1

h(g(f)(x)))=√(2x+1)

Answer 2

[2(x + (1/2))]^1/2
