HPC Unit 7 Polynomial & Rational Functions Review

Select all statements that apply to this polynomial.

• This is an odd degree function.

• This is an even degree function.

• The leading coefficient is positive.

• The leading coefficient is negative.

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

• -1

• -3

• -120

• 4

What is the leading coefficient?

• Positive 
• Negative

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

Which of the following could be the equation of this graph in factored form?

• 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)²(x-2)(x+4)
• f(x) = (x+4)(x+1)²(x-2)(x-4)
