Question 752691
Form the compositions and judge from those.


f o g:

{{{f(g(x))=(3(g(x))+2)^(1/2)=(3(x^2+3)+2)^(1/2)}}}
={{{(3x^2+9+2)^(1/2)=(3x^2+11)^2}}}
{{{highlight(f(g(x))=(3x^2+11)^(1/2))}}}


What can the values of x be and what must not be allowed for the values of x?
No restriction for f(g(x)).  All real numbers are allowed.


How about g(f(x))?
