· F is a function and f’ is the derivative of that function. Since f’ is also a function, it too can have its own derivative. It would be f’’.

· Recall that the derivative of a function tells you weather a function is increasing or decreasing.

· When tangent slops are increasing the graph of f is concave up.

· When tangent slops are decreasing the graph of f is concave down.

**· A point on the graph of a function where the curve changes concavity is called an inflection point.**

Since our class only got an intro to the lesson, that's about all I can tell you guys. The rest of the lesson should be resumed on Tuesday.

See all of you in class tomorrow. BYE!

Oh yeah the next scribe is…

*VAN!*
