Question

I need to know what is (f/g) (x). Please it is very hard to do

Answer 1

The given functions are:

$\begin{gathered} f(x)=x \\ g(x)=2x+4 \end{gathered}$

And the question is what is (f/g)(x), thus:

$(\frac{f}{g})(x)=\frac{f(x)}{g(x)},\text{ where g(x)}\ne0$

Replace the known functions:

$(\frac{f}{g})(x)=\frac{x}{2x+4_{}},x\ne-2$
