Problem 2 Got It? The graph of f(x) is shown.

Recall: The maximum number of turning points of a polynomial function is always one less than the degree of the function.

10

Problem 2 Got It? Use turning points to explain why the graph does not show all of the real zeros of the function.

A 5th-degree polynomial has 5, 3, or 1 turning points. Three are visible, so there must be two more.

A 5th-degree polynomial has 4, 2, or 0 turning points. Three are visible, so there must be one more.
