Question 757410
Not know exactly what you mean for g(x), but if you mean this:
{{{(f + g)(x )}}} when {{{f(x)=2x+5}}} and {{{g(x)=4/x-2}}}


The the composition you indicate is 2x+5+(4/x)-2
={{{2x+(4/x)+3}}}


The domain then is the set of Real Numbers {{{x<>0}}}.
Using inequality to express this domain,
{{{x<0}}} and {{{x>0}}}
(Used "and" because domain is a set and we want to include all members of the set).
