f(x)= square root of x, g(x)= cube root of 1-x

These are my answers, but I am not sure about them and I only figured out one domain... that is the part that really confuses me. Help please!

a) 5th root of 1-x

Domain?

b) The cube root of (1 minus the square root of x)

Domain?

c) Fourth root of x

Domain= [0, infinity]

d) The cube root of (1 minus the cube root of 1 minus x)

Domain?

b.same argument

c. you cannot take the even root of a negative number, so you are correct.

d. same a,b
