Suppose that $\displaystyle \lim_{x\rightarrow -2}{f\left(x\right)}=-3$ and $\displaystyle \lim_{x\rightarrow -2}{g\left(x\right)}=3$ . Then answer the following questions.

  1. Find $\displaystyle \lim_{x\rightarrow -2}{{{f\left(x\right)+1}\over{x+1}}}$.

    $-\infty$ Does not exist. 2 $\infty$

  2. Find $\displaystyle \lim_{x\rightarrow -2}{{{f\left(x\right)+7}\over{g\left(x\right)+1 }}}$.

    4 1 $\infty$ Does not exist. $-\infty$

  3. Find $\displaystyle \lim_{x\rightarrow -2}{\left(f\left(x\right)-2\,x^2-x\right)\, \left(g\left(x\right)+2\right)}$.

    Does not exist. −45 5 −9

  4. Find $\displaystyle \lim_{x\rightarrow -2}{\left(g\left(x\right)+f\left(x\right)-3 \right)^2}$.
