The first thing that should be mentioned is that the one-to-one correspondence howler is not in the textbook per se, but in some accompanying guide. Gareth's link shows pages 5 to 10 of such a guide for section 2-1 of the book. I found an "answers" link for this particular guide which reproduces pages 5 to 9 as pages 6 to 10 (with answers) but replaces the offending page 10 with a page 11 that is different (subheading "Mappings" instead of "Real Number Relations and Functions") and makes no mention of the "correspondence". My guess is that the howler was in an early version of the guide that was subsequently replaced.

contains the offending thing, though I have no particular evidence that it isn't fabricated. It does indeed say "Glencoe Algebra 2" on its pages.
