The function f (x) e using elementary functions. an antiderivative, but there is no nice way to express it Let's use Geogebra CAS to find the definite integral a) Use the command x- Value, End x- Value). b) Approximate the area with 8, 16, 100, and 1000 rectangles using representative points of your choosing (e.g., left endpoints, right endpoints, midpoints) and the command RectangleSum(Function, Start x- Value, End x- Value, Number of Rectan- gles,Position for rectangle start). (NOTE: The Position for rectangle start is O for left endpoints, 1 for right endpoints, and 0.5 for midpoints.) c) Compare the approximations found in (b) to the area found in (a). What happens as you increase the number of rectangles? Submit your response along with a screenshot of your calculations from (a) and (b).
