a. Estimate the total number of cattle that were culled from mid-February through mid-October. Use rectangles that are one month in width, starting with mid-February.
Using the value of the function at the left endpoint of each rectangle as the height for each rectangle, the total number of cattle is approximately 640,000.
(Round to the nearest thousand as needed.)
Using the value of the function at the right endpoint of each rectangle as the height for each rectangle, the total number of cattle is approximately.
