Consultation hours this week - and, a detail on problem 32

I suspect there will not be demand for my consultation hours this week - but I will show up if you drop me an e-mail.

Now, more than one of you have had issues with the inflection point in Problem 32. The (-1/2,0) means the interval, not point coordinates. So the x₀ where the function inflects, should be strictly between -1/2 and 0.
