Polynomial practice

Identify the zeros:

• x=-2, x=-1, x=0
• x=-2, x=0
• x=-1, x=0, x=2
• x=-2, x=0, x=1

Which of the following could be the equation of this graph in factored form? (Careful-pay attention to multiplicity.)

• f(x) = (x-4)(x-1)²(x+2)(x+4)

• f(x) = (x-4)(x+1)²(x+2)(x+4)

• f(x) = (x+4)(x+1)(x-2)(x+4)

• f(x) = (x+4)(x+1)²(x-2)(x-4)

Select polynomial whose zeros and degree are given. Zeros: – 5(multiplicity of 3), 9(multiplicity of 2), – 2, 4 Degree: 7

• (x + 5)(x - 9)

  (x + 2) (x - 4)

• (x + 5)³(x - 9)² (x + 2)(x - 4)⁷

• (x + 5)³(x - 9)²

  (x + 2)

• (x + 5)³(x - 9)²

  (x + 2)(x - 4)
