WHICH IS BETTER? Part One Below are different sets ofrectangles to approximate the area under a curve for the same interval Look at the three different sets of rectangles and decide which will best approximate the area under the curve of this function for a S a: S b Homework Help; a. Explain why your choice will determine the best approximation for the area, 13. Will left endpoint rectangles always be an underestimate for any function? Explain. ,v v .V a DA (l by (l I)? Left Endpoint Rectangles Midpoint Rectangles Right Endpoint Rectangles
