Question

Which of the following functions has a vertical asymptote at a = -2, a horizontal asymptote at f(a) OA. f(x) = OB. f(x) Oc. f(x) OD. f(x) 1 4 *12 1 1 1 1, and a root at a 2?

Answer 1

The only function below that has a root at x=2 is the one in letter C. It also happens to have the asymptotes they asked.

As for the root:

`\begin{gathered} 0=(4)/(x+2)-1 \\ (4)/(x+2)=1 \\ x+2=4 \\ x=4-2 \\ x=2 \end{gathered}`

Answer: letter C
