Correction to image? : In right hand image for y2 there does exist an x value for which y2 = f(x). So y2 should be removed from the image and the description on the main page. Also the f:X1->Y1 and f:X2->Y2 are obsolete and appear to have been copied from the other similar image on the main article page.
