For the following exercises, consider the function f ( x ) = | x | . 25. Use the preceding exercise to find the exact value of the area between the x-axis and the graph of f over the interval [-1, 2] using rectangles. For the rectangles, use the square units, and approximate both above and below the lines. Use geometry to find the exact answer.
