polynomial graph

• y =  ^_(x + 2)(x - 1)²

• y = -(x - 2)(x + 1)²

• y = (x - 2)(x + 1)²

• y = -x³

• y = x(x - 3)(x - 2)

• y = x(x - 3)² (x+2)

• y = x(x + 3)² (x - 2)

• y = -x(x + 3)² (x - 2)

Write a 4th degree polynomial function with:
*a positive leading coefficient
*zeros: 9, 3, -2, 0

• y = x(x - 9)(x - 3)(x + 2)

• y = x(x + 9)(x + 3)(x - 2)

• y = -x(x - 9)(x - 3)(x + 2)

• y = -x(x + 9)(x + 3)(x - 2)

f(x) = (x-4)²(x+1)

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
