Also, check out this fella's archive of videos for calculus students. When you get there, check out the first one. Also, if you ever have a really thorny problem he says he'll solve for you and make a video about it. Hmm ... that sounds like a good idea for a student assignment ... aren't you glad I'm on leave? ;-)
I don't know if I'm right, but I think he made a slight error with the range. I think the domain is correct since it goes on forever in both directions, but isn't the range [0, positive infinity) since the y-outputs never cross below the axis?
ReplyDeletethis is for y = x^2 btw.
ReplyDelete.:.j + me.:. Way to go! You're right, he was wrong. Excellent catch! Make certain you share this with the rest of the class f2f. Be proud, you've got a good eye. ;-)
ReplyDeleteCheers!
