for the given functions f & g find the specified value of the following functions and state the domain of each one.
f(x)=2+6/x; (g)x 6/x
a. (fg)(3)=
what is the domain of fg?
b. (f/g)(6)=
what si the domain of f/g?

precal 
Henry,
a. (fg)(3)=(2+(6/3))  6/3 = 4  2=2.
Domain: All real values of X except 0.
0 > X > 0.
b. (F/G)(6)=((2+(6/6)) / (6/6) = 3/1=3.
Domain: All real values of x except o.
0 > X > 0.
