Describing Graphs of Polynomial Functions

Describing Graphs of Polynomial Functions 1.4 - Solution

arrow_back Return to Describing Graphs of Polynomial Functions
a
The number of turning points for a polynomial function of degree nn can be at most n1.n-1. Thus, if the degree is 33 the turning points can be 2.2.
b

Using the same rule as above this function can have 66 turning points sin the degree is 7.7.

c

The function is 8x+5 8x+5 is of degree 1.1. Since the turning points are one less that the degree, the number of turning points is 0.0.
