Remember to look at your roots, multiplicity, and end behavior!!

Use your notes!

• y = ^_(x + 2)(x - 1)²

• y = -(x - 2)(x + 1)²

• y = (x - 2)(x + 1)²

• y = -x³

Remember to look at your roots, multiplicity, and end behavior!!

Use your notes!

• (-2.55, 0), (2.55, 0)

• (-3, 0), (-2, 0), (2, 0), (3, 0)

• (0, 36)

• (0, -3), (0, -2), (0, 2), (0, 3)

Which equation MOST LIKELY matches the graph?

Remember to look at your roots, multiplicity, and end behavior!!

Use your notes!

• y = x⁴ - x³ + 3x² + 2

• y = -x⁴ + x³ + 5x + 2

• y = x³ - 2x² + 1x + 3

• y = -x³ - 2x² + 1x + 3

In the above graph, which root has a multiplicity of 2?

Remember to look at your roots, multiplicity, and end behavior!!

Use your notes!
