End Behavior:

f(x) = -2x 3 - 4x2 + 30x

Mwtipli Df Roots

What do you notice about the roots (zeros) that repeat?

F(x) = (x + 2)4(x -1)

F(x) = (x - 2) 3 (x + 5)

X

F(x) = (x - 4)2 (x -1)2

X

F(x) = -0.3(x + 3)4(x - 2)2

X

Roots that have an odd degree ______ the x-axis. Roots that have an even degree are ______ to the x-axis.
