Question 1185852: Consider the function
F(x)=x^2-5, g(x)=2x+1
Find the domain for f g and for g f in interval notation , and simplify the formula

"f g" and "g f" are not standard notation; we don't know what those function are.

(f*g)(x) and (g*f)(x)?
(f(g(x)) and g(f(x))?
or even
(f+g)(x) and (g+f(x)
etc., etc....

Re-post so we know what the problem is.
