Homework Help: Calculus

Posted by Elisabeth on Friday, June 25, 2010 at 2:04am.

Is x^2 - 2x
1 to 1?

I keep getting yes every way I try to work it. Book says no. In the end, I get (with x1=1 and x2=-1 <- I use these numbers because of the x^2) f(x1) = -1 and f(x2)=3. I can't seem to find if x1 = x2

(btw, I know that by the graph it is not, but I am trying to work it out the books way)
