Lesson #21 Day 2: Zeros of Polynomials Practice

Which of the following can be used to say where a function "crosses through the x-axis?"

• Zeros

• X-Intercepts

• Roots

• All of the Choices

What does "multiplicity" mean on graphs?

• The y-intercept is at (0,0).

• The graph has more than one maximum.

• The graph goes to positive infinity.

• The x-intercepts count more than once.

Based on the graph, list the roots as points.

• (-3, 0) and (-2, 0)

• (-1, 0) and (2, 0)

• (0, -1) and (0, 2)

• (5, 0)

Based on the graph, write the equation in factored form.

*HINT: Pay attention to multiplicity/bounces*

• (-3, 0) (5, 0) (1, 0)

• (0, 0) (2, 0) (-7, 0)

• (3, 0) (-5, 0) (-1, 0)

• (-3, 0) (5, 0)

• There are invisible zeros.

• There are no zeros.

• It has only one zero at (-6, 0).

• It has multiplicity (two zeros) at the point (-6, 0).

The given graph corresponds to which equation in factored form?

• 0

• 3

• 2

• 1

Which of the following statements can you conclude from the graph's end behavior?

• Even degree, positive leading coefficient

• Odd degree, positive leading coefficient

• Even degree, negative leading coefficient

• Odd degree, negative leading coefficient
