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.

  • math -

    (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

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