If a zero of a polynomial function has multiplicity 4 that means:

• The x intercept is at (4, 0)

• The graph will "bounce back" at that zero

• The graph will "pass through" at that zero

• Zeros cannot have multiplicity of 4

4 is a(n)...

• Absolute Maximum

• Absolute Minimum

• Local Maximum

• Local Minimum

How many real zeros does the function have?

• None

• 2

• 3

• 4
