Question

for the given functions f and g, find the specified value of the following functions and state the domain of each one. f(x)=2+3/x; g(x)=3/x
a.(f-g)(2)=
b.(f/g)(3)=
how do I do this? I need help! it throws me off because of it being in fraction form.

Answer 1

(f - g)(2)
= f(2) - f(2)
= 2 + 3/2 - 3/2 = 2

(f/g)(2)
= (2+3/2) / (3/2)
= (7/2) / (3/2)
= (7/2)(2/3) = 7/3

Answer 2

thank you so much....what would be the domains of these though?
