Question

Quizplus · Accepted Answer

The turning point of the given polynomial function within the interval [0,1] can be found using a graphing calculator. By graphing the function and analyzing its behavior within the specified interval, we can identify the turning point's coordinates. The correct answer, (0.81, 120.74), indicates the x-coordinate of the turning point is approximately 0.81, and the corresponding y-value is approximately 120.74, which is the only option that falls within the given interval.
