Chapter 2.5, Problem 13PE

For Exercises 13-16, refer to the graph of the function and complete the statement. (See Example 1)

$\begin{array}{l}\text{a}\text{. As }x\to -\infty ,f\left(x\right)\to \_\_\_\_\_.\\ \text{b}\text{. As }x\to 4^{-},f\left(x\right)\to \_\_\_\_\_.\\ \text{c}\text{. As }x\to 4^{+},f\left(x\right)\to \_\_\_\_\_.\\ \text{d}\text{. As }x\to \infty ,f\left(x\right)\to \_\_\_\_\_.\\ \text{e}\text{. The graph is increasing over the interval}\left(\text{s}\right)\_\_\_\_\_.\\ \text{f}\text{. The graph is decreasing over the interval}\left(\text{s}\right)\_\_\_\_\_.\\ \text{g}\text{. The domain is}\_\_\_\_\_.\\ \text{h}\text{. The range is }\_\_\_\_\_.\\ \text{i}\text{. The vaertical asymptote is the line}\_\_\_\_\_.\\ \text{j}\text{. The horizontal asymptote is the line}\_\_\_\_\_.\end{array}$
