This video tutorial explains turning points in polynomial functions, focusing on how they occur at maximum or minimum values. It details the maximum number of turning points as the degree minus one, regardless of whether the function is even or odd. For even-degree functions, there is at least one turning point due to similar end behaviors, while odd-degree functions can have zero turning points due to opposite end behaviors. The video concludes by summarizing these concepts.

What is a turning point in a polynomial function?

• A point where the function has a discontinuity

• A point where the function reaches a maximum or minimum

• A point where the function intersects the x-axis

• A point where the function is undefined
