Answer:
A.zero and zero
Step-by-step explanation:
The attached image shows the complete question.
The maximum and minimum points of a curve are points in which the slope equal to zero. The maximum point is the point with the highest value of y and a slope of zero while the minimum point is a point on the curve with lowest value of y and a slope of 0.
The image attached shows point A and point B. Point A is the maximum because it has a slope of 0 and highest value of y. At point B, the curve has a slope of zero with the smallest y-coordinate
