CPM Homework Help : PC Problem 7-10

Sketch the graph of a function (you do not need to find an equation for it) that is increasing on $\left(−∞, −2\right)$ and $\left(2, ∞\right)$ , decreasing on $\left(−2, 2\right)$ , concave down on $\left(−∞, 0\right)$ , and concave up on $\left(0, ∞\right)$ .

Possible Answer:

Curve coming from lower left, turning down at (negative 2, comma 2), passing through the origin where it changes concavity, turning up at (2, comma negative 2), continuing up & right.
