the problem is:

Write for fg and gf and find a) the domain and b) the range of each function

22.
f(x)= 2x
g(x)=x^2
 
Do you know what function notation means?

If f(x) = 2x, then f(0) = 2*0 and f(12) = 2*12 and f(dog) = 2*dog

You do f(g(x))

Write for fg and gf...
Does "fg" mean "f(x) times g(x)", or "(f compose g) of x"?

Thank you.

Eliz.
