Graph of a cubic polynomial that falls to the left and rises to the right with x intercepts negative 3, negative 1, and 3 Which of the following functions best represents the graph? a f(x) = x3 + x2 − 9x − 9 b f(x) = x3 + 4x2 − x − 4 c f(x) = x3 + 3x2 − 3x − 9 d f(x) = x3 + 2x2 − 4x − 8

The correct answer is Choice A.

If you graph the function on a graphing calculator, you will find that it matches all of the necessary parts. If falls to the left and rises to the right.

It also has zeros at -3, -1 and 3.
