There was a typo to this problem initially. It should read...

Suppose and .

I'm guessing we need to use the Intermediate Value Theorem to show that if there exists then . And then somehow use this to show that and ?? - Nov 14th 2010, 11:14 AMDrexel28

Well, my professor never told us but judging by the position of the proof in my notes I think we are trying to help prove the following theorem:

If and are intervals and is continuous, then the range of is an interval.

So is it possible that is an interval?? - Nov 14th 2010, 04:12 PMDrexel28
