If the limit of f(x) as x approaches a exists, and the limits are equal to f(a) at the point and from both sides, then f(x) is continuous at x=a
[f(b) - f(a)] / (b-a)
How fast f(x) is increasing or decreasing at the point x = a
2 True/False Questions
Mean Value Theorem → If f(x) is continuous in an interval [a, b] then somewhere on the interval it will achieve every value between f(a) and f(b); if f(a) is less than or equal to M, which is less than or equal to f(b), then there exists one value c in the interval [a, b] such that f(c) = M.
Intermediate Value Theorem → A generalization of Rolle's Theorem. If f(x) is continuous on the closed interval [a, b], differentiable on (a, b), then there exists one c on (a, b) such that f'(c) = [f(b) - f(a)] / (b-a)
