How does the multiplicity of a zero affect the graph of the polynomial function? Select answers from the drop-down menus to corr
miskamm [114]

Answer:

3 points: x = 1, x = 2 and x = 4

1 point: x = 6

Cross

Step-by-step explanation:

Points to remember:

  • A zero of odd multiplicity will cross through the x-axis
  • A zero of event multiplicity will only touch the axis i.e. be tangent to it.

The given zeros are:

  • 1 with multiplicity of 1 (Odd Multiplicity)
  • 2 with multiplicity of 3 (Odd Multiplicity)
  • 4 with multiplicity of 1 (Odd Multiplicity)
  • 6 with multiplicity of 2 (Even Multiplicity)

The graph will cross x-axis at zeros with odd multiplicity. Since zeros with odd multiplicity are 3, the graph will cross the x-axis at <u>3 points</u>: x = 1, x = 2 and x = 4

Similarly, the zero of even multiplicity is 1, so the graph will touch the x-axis at <u>1 point</u> only: x = 6

At the zero of 2, the graph of the function will <u>cross</u> the x-axis.
