Graphing Polynomial Functions

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

• -1

• -3

• -120

• 4

What are the
zeros of the polynomial
y = 3(x + 4)(x + 1)(x - 3)?

• -4, -1, 3

• 3, -3, 4, 1

• 4, 1, -3

• 3, -4, -1, 3

• Even Degree
  - Leading Coeff.

• Even Degree
  + Leading Coeff.

• Odd Degree
  - Leading Coeff.

• Odd Degree
  + Leading Coeff.

The domain of a polynomial function is always (-∞, +∞).

• True

• False

What is the factored form of a function if it has zeros of 2, 3 and -1?

• (x-2)(x-3)(x+1)

• (x-1)(x-2)(x-3)

• (x-1)(x+2)(x+3)

• (x+1)(x+2)(x+3)

The degree of the polynomial determines the number of roots.

• True

• False

What is the leading coefficient?

• Positive 

• Negative

f(x)=(x+4)(x-3)(x-2)

List the zeros for this function.

• x=-4, x=3, x=-2

• x=-4, x=3, x=2

• x=-4, x=3, x=-2

• x=4, x=3, x=2

What is another way to say "where a function crosses the x-axis"?

• x-intercept

• zero

• root

• all of these.

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
