Suppose that f is an positive-valued, increasing function on the interval from x = 0 to x = 4, and that we use the method of rectangles to approximate the area between the curve and the x-axis. If we use the usual method of taking the right endpoint to be the height of each rectangle, then our approximation will be an _________
