define and explain rolles thm ​

Answer 1

Answer:

Step-by-step explanation:

Rolle's theorem, in analysis, special case of the mean-value theorem of differential calculus. Rolle's theorem states that if a function f is continuous on the closed interval [a, b] and differentiable on the open interval (a, b) such that f(a) = f(b), then f′(x) = 0 for some x with a ≤ x ≤ b.

Answer 2

Step-by-step explanation:

Rolle's theorem states that if a function f is continuous on the closed interval [a, b] and differentiable on the open interval (a, b) such that f(a) = f(b), then f′(x) = 0 for some x with a ≤ x ≤ b.

Rolle's theorem states that if a function f is continuous on the closed interval [a, b] and differentiable on the open interval (a, b) such that f(a) = f(b), then f′(x) = 0 for some x with a ≤ x ≤ b.Rolle's Theorem, as for most well-stated theorems, all the hypotheses are necessary to be sure of the conclusion. In the graph at right above, y = g(x) has a corner and g (1) does not exist, so just one hypothesis fails at just one point.
