Use a graphing calculator to find the coordinates of the turning points of the graph of the polynomial function in the given domain interval. Sometimes turning point is defined as local maximum or minimum only. A turning point is a point where the graph of a function has the locally highest value called a maximum turning point or the locally lowest value called a minimum turning point.

There are three different ways to find that but in all cases we need to start by finding the equation finding out the values of a and b. B2a x 1 23 16 - b Now use your calc to find the y-coordinate of. However this depends on the kind of turning point.

Polynomials of odd degree have an even number of turning points with a minimum of 0 and a maximum of n-1. First derivate your function. I need to find the turning points ie.
