Intermediate Value Theorem

If the function f(x) is continuous on [a,b], then f(x) achieves every value between f(a) and f(b) in the open interval (a,b).

Mean Value Theorem

If the function f(x) continuous on [a,b], and the first derivative exists on the interval (a,b), then there is at least one number x = c in (a,b) such that f’(c) = [ f(b)-f(a) ] / (b-a).

Rolle’s Theorem

Same as mean value theorem but if f(a) = f(b), then there is at least one number x = c in (a,b) such that f’(c) = 0.
