 Using a Table of Slopes to Sketch a Graph(3.3 #73)


Using what we know about the first derivative we can sketch a graph from a table of slopes.  I also show how to put the table into your calculator to see a graph of f'.

First Derivative, Increasing, Decreasing, and extrema (3.3 (p187) #11, 15, 17, 27, 35

 First Derivative, Increasing, Decreasing, and extrema (3.3 (p187) #11, 15, 17, 27, 35

The first derivative can find relative extremes when it changes from negative to positive (min) or positive to negative (max).  Here are 5 quick examples:

#11 -  0:00

#15 - 2:11

#17 - 3:28 

#27 - 6:00

#35 - 8:08

Summer Topic: Domains

Not all functions can take any number. The set of numbers that the function can accept is called a domain.  Here we review how to analyze a ...
