Suppose a polynomial function has degree n What is the MAXIM

Suppose a polynomial function has degree n. What is the MAXIMUM number of turns (relative minima maxima) its graph can have? A) 0 B) n C) n - 1 D) n - 1

Solution

Since, we know that the graph of polynomial of degree n, has possible maximum humber of turning points is one less than of its degree.

Therefore, the maximum number of turns of a polynomial of degree n is ( n - 1).
