...determine the area under a curve. For example, the integral of a continuous function f that takes only positive values between the real numbers a and b , where a less than b , is the area bounded by the graph of y equals f of x , the x -axis, and the two vertical lines x equals a and x equals b , as illustrated by the shaded part of Figure 5.
