1. Hand back test on Chapter 4.
2. Today we will try to come to an intuitive understanding of the following concepts:
(A) increasing function
(B) decreasing function
(C) constant function
(D) concave up
(E) concave down
(E) point of inflection
3. Draw a curve on the blackboard and discuss topics above:
4. When is the function increasing?
If f'(x) > 0 Then f(x) is increasing.
If f'(x) < 0 Then f(x) is decreasing.
If f'(x) = 0 Then f(x) is constant.
5. Examples:
Find the intervals where each of the following functions are increasing and decreasing:
