IM Alg2.2.14 Practice: What Do You Know About Polynomials?

We know these things about a polynomial function, f(x): it has exactly one relative maximum and one relative minimum, it has exactly three zeros, and it has a known factor of (x-4). Sketch a graph of f(x) given this information.

Mai graphs f(x) polynomial function.

has three linear factors  and . But she makes a mistake. What is her mistake?

Here is the graph of a polynomial function with degree 4.

Select all of the statements that are true about the function.

Select all that apply
  • A
  • B
  • C
  • D
  • E
  • F
  • G
Check my answer (3)

State the degree and end behavior of . Explain or show your reasoning.

Is this the graph of  or ? Explain how you know.

Kiran thinks he knows one of the linear factors of . After finding that , Kiran suspects that  is a factor of , so he sets up a diagram to check. Here is the diagram he made to check his reasoning, but he set it up incorrectly. What went wrong?

The polynomial function   has a known factor of . Rewrite  as a product of linear factors.
