For the piecewise function, find the specified function value: for x < -1, 7) f(x) = for x > -1 f(-2).
Use a graphing calculator to graph the function. Find any relative maxima or minima. 8) f(x) = -x^3 – 15x^2 – 6x.
Write the equation for the piecewise function.

Evaluate $f(-3), f(0)$, and $f(2)$ for the piecewise defined function. Then sketch the graph of the function.$$f(x)=\left\{\begin{array}{ll}-1 & \text { if } x \leqslant 1 \\7-2 x & \text { if } x>1\end{array}\right.$$

Graph each piecewise function. See Example $7 .$$$f(x)=\left\{\begin{array}{ll}2 & \text { for } x>1 \\-2 & \text { for } x \leq 1\end{array}\right.$$
