Really need help with my algebra function homework

if f(x) = x^2 and g(x) = square root of x, then find (f times g) (x) and (g times f) (x) and state the domain for each.


2. Let f(x) = 1/x
Find (f times f) (x) and state the domain

f(x ) = x^2 and g(x) = x^(1/2) so (f*g((x) = x^5/2. and this is the same as (g*f(x).
However I think you're looking for (f o g)(x) = x and (g o f)(x) = x

#2. If you do (f o f)(x) then you get 1/(1/x) = x.
