Estimate the area A of the region between the graph of f(x) = > and the x- axis from x = 0 to x = 1 by using approximationg rectangles. Draw the region on a piece of paper first. First, divide the region into four vertical strips with equal widths. Find an upper bound for A using rectangles determined by the right edges of strips. Find a lower bound for A using rectangles determined by the left edges of strips. Round final answers to three decimal places. Number
