Last time we have done Example 1,there is not only one function actually,because x—axis is the function y=0. Example 1:Find the area between f(x) =x—x~2+2 and x—axis. Could you do Example 2 by using hand-work in Example 1? The graphs of f(x)=x~2 -2 and g(x)=x are shown in the figure generated by Geometer’s Sketchpad 4.06.
