Understanding Rolle's Theorem Rolle's theorem applies to a function f(x) that is continuous and differentiable on the interval [a, b], with equal values at endpoints (f(a) = f(b)). It guarantees at least one point c in (a, b) where the derivative of the function equals zero. This principle forms a foundation for analyzing polynomial or trigonometric functions under specific conditions.
Verifying Continuity and Differentiability To verify Rolle’s theorem for any given problem, first ensure that f(x) is continuous over [0, 8] using its definition. Next confirm it is differentiable within this range by checking if derivatives exist everywhere between these points. These steps establish whether basic criteria are met before proceeding further into calculations.
Checking Endpoint Values Equality The next step involves confirming endpoint equality: calculate both f(0) and f(8). For example here solving equations like x^(2/3)-2*x^(1/3), ensures outputs match ensuring prerequisites hold true mathematically validating initial assumptions made earlier regarding boundary
