Graph the function LaTeX:  \displaystyle f(x)=\begin{cases} \frac{x}{5} + 7,& x \leq -4\\ 10 - \frac{3 \left(x - 1\right)^{2}}{5},& -4 < x < 2\\ 2 - x,& x \geq 2 \\ \end{cases}

The graph has three parts. It is a line on LaTeX:  \displaystyle (-\infty, -4] , a parabola on LaTeX:  \displaystyle (-4,2) , and a line on LaTeX:  \displaystyle [2, \infty) . Graphing each part gives:
