A)State an interval in which the x -coordinate of the maximum turning point on the graph of y=−x(x+2)(x−3) must lie.

B)Use a numerical method to zoom in on this interval and hence estimate the position of the maximum turning point of the graph with the x -coordinate correct to 1 decimal place.

Here's one approach:
