Answer:
Explanation:
There is a relationship between the degree of the polynomial and the number of times its graphed curved changes direction> this change is called turning point which is a point where the graph changes from increasing to decreasing or from decreasing to increasing
A polynomial of n degree will have n-1 turning points
ex: f(x)=x³+3x²+x+1
degree of polynomial is 3, it has 2 turning points (3-1)
