A point of inflection occurs when the second derivative changes sign. Taking the derivative of the given function twice, we get f''(x) = 6⁹ F1F10. This is a constant, and it never changes sign. Therefore, there is no point of inflection, and the answer is D: None exist.

The Function F(x) = X9 - 9 Has a Point

The Function F(x) = X⁹ - 9 Has a Point
