If f(x)=x-3/x and g(x)=5x-4, what is the domain of (f•g)(x)

Step-by-step explanation:                                                         3

(f•g)(x) has either the form  ( [x - 3] /x)(5x - 4) or the form (x - )(5x - 4)

                                                                                                     x

Please use parentheses to eliminate any ambiguity.

Focusing on the first possibility:

(f•g)(x) = ( [x - 3] /x)(5x - 4)  is defined for all x except x = 0, as we cannot divide by 0.
