The cubic function can be graphed using the function behavior and the points.

$\begin{array}{c} x & y \\ - 2 & - 10 \\ - 1 & - 3 \\ 0 & - 2 \\ 1 & - 1 \\ 2 & 6 \end{array}$

The cubic function can be graphed using the function behavior and the selected points.

Falls to the left and rises to the right

$\begin{array}{c} x & y \\ - 2 & - 10 \\ - 1 & - 3 \\ 0 & - 2 \\ 1 & - 1 \\ 2 & 6 \end{array}$
