Question

Quizplus · Accepted Answer

The maximum number of turning points of a polynomial function is one less than its degree. Since $f(x) = 9x - x^3$ is a cubic polynomial (degree 3), it can have up to 2 turning points.

Determine the Maximum Number of Turning Points of F f(x)=9x−x3f ( x ) = 9 x - x ^ { 3 }f(x)=9x−x3

Determine the Maximum Number of Turning Points of F $f ( x ) = 9 x - x ^ { 3 }$
