I need help with this problem. I do not know how to solve this one.
Consider the functions:  f(x) = square root 3(x-1),  g(x) = x^3+1

Now find each of the following if possible
(a) fog
(b) gof
(c) (fog)(0)

[tex]f \circ g=\sqrt{3(x^3+1-1)}=\sqrt{3x^3}\\ g \circ f=(\sqrt{3(x-1)})^3+1=3(x-1)\sqrt{3(x-1)}+1\\ (f \circ g)(0)=\sqrt{3\cdot0^3}=\sqrt0=0[/tex]
