Given f (x )equals 5 x plus 9 and g (x )equals 3 x squared, first find f plus g, f minus g, fg, and StartFraction f Over g EndFraction . Then determine the domain for each function.

Answer with Step-by-step explanation:

We are given that

f(x) is linear function

Domain of f(x)=R

g(x) is a quadratic function

Domain of g(x)=R

Domain of (f+g)=R

(f-g)(x)=f(x)-g(x)=

Domain of (f-g)=R

Domain of fg=R

The function is not defined where g(x)=0

Domain of f/g=R-{0}
