Essay

In the problems below, find any relative maximum or minimum values of each function.
-Given $f(x)=\frac{6}{x^{2}-9}$ , find a) the intervals for which $f(x)$ is increasing and decreasing, b) relative maximums and relative minimums, $\mathrm{c}$ ) intervals for which $\mathrm{f}(\mathrm{x})$ is concave upward and concave downward, and d) points of inflection. Sketch the curve.
