Drill
Look at the following graph. Notice that it is:
1. continuous on [-2, 2]2. differentiable on (-2, 2)
3. and f(2) = f(-2)
Find the value of c, for which f (c) = 0
1. Draw two more graphs that have the same three properties as above, including at least one place wheref (c) = 0, but which look different.
2. Try to draw a graph that has the same three properties as above, but does NOT have a value c where f (c) =
0

Notes 4.2
First we have to talk another theorem
ROLLES THEOREM
_________________________ has three stipulations:
1. f is ______________________________________________________________________
2. f is ______________________________________________________________________
3. _________________________________________________________________________
If f satisfies the above three properties, then there is a numberc in (a, b) such that
____________________________________________________________________________
MEAN VALUE THEOREM:
_________________________ has two stipulations:
1. f is _____________________________________________________________________________
2. f is _____________________________________________________________________________
If f satisfies the above three properties, then there is a numberc in (a, b) such that
___________________________________________________________________________________

GRAPHICAL EXPLANATION:
EX 1: Verify that the function below satisfies the MVT, then find all numbers c that satisfy the conclusion ofthe MVT: f(x) = x3 on [-2, 2]
