Answer:

f(x)=x^2+4\\g(x)=4x

(f+g)(x)=x^2+4+4x\\(f+g)(x)=x^2+4x+4

------------------------------------------------------------------

(f-g)(x)=x^2+4-(4x)\\(f-g)(x)=x^2+4-4x\\(f-g)(x)=x^2-4x+4\\

-----------------------------------------------------------------

(f*g)(x)=(x^2+4)(4x)\\(f*g)(x)=4x^3+16x

-----------------------------------------------------------------

(\frac{f}{g})(x)= \frac{x^2+4}{4x} \\
