IntMath forum | Applications of Differentiation

Wrote you earlier today.  Confusion might come from Example 4.  Three lines before the graph for that example you write if x > -1 the second derivative is greater than 0.  Should it be if x >1?  Just wondering.

What I've done so far

@phinah: Yikes! Thank you for pointing out the typo - you are totally correct.

I fixed it just now, (You may need to refresh that page to see the update).

Sorry about the confusion!
