Use the end behavior determined from the equation f(x) = x³ + x² - 4x -4 and the zeros from the equation f(x) = (x+1)(x-2)(x+2) to find the graph of the function (these equations are the same in different forms).

• A (up down) (zeros: -2 & 2)

• B (down up) (zeros: 0)

• C (down up) (zeros: -2, -1, & 2)

• D (up up) (zeros: -1 & 5)

The function shown has:

• Degree two with positive leading coefficient.
