B 5 turning points. For example: The polynomial function y= ×^6 + 3x^5 +
4x^2 + 12 has six turning points. The degree of the polynomial is 6, which means that it has 6-1=5 turning points. These are the points where the function changes from increasing to decreasing or vice versa. In other words, these are the points where the derivative of the function equals 0. To find the exact locations of the turning points, you can set the derivative equal to 0 and solve for
