20. Define A(x) to be the area bounded by the x and y axes, the curve y = f(x), and the vertical line at x (Fig. 20). From the figure, it is clear that A(1) 3. 2 A(x) rectangle area Do you think there is a value of x, between 1 and 3. so A(x) = 3? If so, justify your conclusion and estimate the location of the value of x so A(x) = 3. 2 If not, justify your conclusion. Fig. 20
