Label the “turning points”.

Finding the number of turning points in an equation: Step 1: Determine the degree (the largest exponent) Step 2: The most turns a graph can have is one less than the degree Step 3: Find the zeros. (set function equal to zero) Step 4: It will have an exact number of turns if all zeros are real numbers and none are repeated “distinct” Step 5: It will have a maximum number of turns if there are imaginary zeros
