Math Problem Statement
verify rolles theorem for the function f(x)= 1/x^2 in the interval [-1,1]
Solution
Rolle's Theorem states that if a function satisfies the following conditions on a closed interval :
- is continuous on ,
- is differentiable on ,
- ,
then there exists at least one such that .
Analysis of on :
-
Continuity:
The function is not continuous at , as it is undefined there. Therefore, is discontinuous on . -
Differentiability:
Since is discontinuous at , it is also not differentiable on . -
Equal Function Values at Endpoints:
While , the lack of continuity and differentiability means Rolle's Theorem does not apply.
Conclusion:
The function fails the conditions of Rolle's Theorem because it is not continuous and differentiable on the given interval. Thus, Rolle's Theorem cannot be verified for on .
