abs(y)=1-x^2?

thanks

just meas that

*or*.

Therefore you can just draw the graph of , and then draw that graph again, but flipped around the x-axis (which changes the sign of the y-coordinates only).

Of course, the resulting figure is*not*the graph of a*function*, but it is the graph of a*relation*(between x and y). - Apr 26th 2010, 12:09 PMAmer
