If a zero of a polynomial function has multiplicity 3 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

If a zero of a polynomial function has multiplicity 2 that means:

• The graph will "bounce back" at that zero

• The graph will "pass through" at that zero

• The equation is the degree of 2

• The equation is multiply twice

What are the x-intercepts of
f(x)=(x - 10)(x + 10)

• 10

• (10 , 0) and (-10 , 0)

• (0, -10) and (0, 10)

• 0
