3.2 Role’s Theorem
An extreme value must occur if certain things happen in the graph.
If __________________then ________________.
Review: IVT?Continuous. Y-value is in the middle
There exist a c such that f(c) = y.
3.2 Role’s Theorem
An extreme value must occur if certain things happen in the graph.
If __________________then ________________.
If f is continuous from [a, b], f Is differentiable from (a , b) and f(a) = f(b) Then there is at least one “c” value s.t f’(c) = 0.
