Math Problem Statement
f(x) = 1 + (1-x)^4/3 can you apply rolle's theorem on [0,2]
Solution
To determine if we can apply Rolle's Theorem to the function on the interval , we need to verify the three conditions of Rolle's Theorem:
- The function is continuous on the closed interval .
- The function is differentiable on the open interval .
- The function satisfies , where and .
Let's go through these steps:
Step 1: Continuity of
Since , this is a polynomial function and polynomials are continuous everywhere. Therefore, is continuous on .
Step 2: Differentiability of
Polynomials are also differentiable everywhere, so is differentiable on the open interval .
Step 3: Checking if
Now we compute and .
Since , the third condition is satisfied.
Conclusion:
All the conditions of Rolle's Theorem are satisfied. Therefore, we can apply Rolle's Theorem to the function on the interval .
Rolle's Theorem guarantees that there exists at least one such that .
