A cubic with a positive x³ coefficient will have a generally "/" shape, increasing to the right. When your function is evaluated at x=-2, you get (-2)³-2 = -8-2 = -10. These facts are sufficient to help you select the 3rd choice as being appropriate.
... graph that increases from left to right that passes through ordered pairs negative 2, negative 10; negative 1, negative 3; 0, negative 2; 1, negative 1; and 2, 6
This is a cubic function. The end behavior of the graph will increase to the right and decrease to the left.
