Please please help!!! I really need help on this quarion and I keep getting it wrong :(

Marta_Voda [28]

Answer:

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

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

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

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

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

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

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

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