Question

Evaluate the following expression given.

Answer 1

In order to evalute this function, we must substitute x=-2 into the equation. It yields

$\frac{4(-2)+3(-2)+2(-2)+(-2)}{-2}$

By computing the porduct we have

$\frac{-8-6-4-2}{-2}$

which is equat to

$\begin{gathered} \frac{-20}{-2} \\ \sin ce\text{ minus times minus is plus, we have} \\ \frac{10}{2} \end{gathered}$

Finally, the evaluations gives 5.
