My Terrific Students
Just saw this on the class facebook page. One girl found it and many of the kids are talking about ordering it.
Just got this e-mail with the subject "Are you available to help me now?"
I'm still not too sure if I can analyze equations proficiently enough
so I decided to do one more problem, number 18 in the blue textbook on
page 204. However its a daunting problem,f(x) will never be negative
which means its first derivative is always positive as well, which I
believe the 2nd derivative will show that f(x) will have a concave up
at some point. I'm not sure how to find the points though, do I need a
calculator in order to do this problem. The question is 8e^(-x) /
(2e^(-x) + 5e^(-1.5x)) if I'm not mistaken.
I'm going to have a hard time giving all of this up. I love these kids. They keep me young and strong.
