Questions and Answers

What does the Intermediate Value Theorem state?

If f(x) is continuous on the closed interval [a,b] and k is any number between f(a) and f(b), then there is at least one number c in [a,b] such that f(c) = k.

If a function is differentiable, then it is continuous.

True

What is the Fundamental Theorem of Calculus?

Part 1: If f(x) is continuous on I, then d/dx (integral from a to x of f(t) dt) = f(x). Part 2: If f is continuous on [a,b] and F is an antiderivative of f, then integral from a to b of f(x) dx = F(b) - F(a). Signup and view all the answers

Study Notes

Intermediate Value Theorem

Ensures that for any continuous function ( f(x) ) over the interval ([a,b]), a value ( k ) between ( f(a) ) and ( f(b) ) will exist at some point ( c ) in ([a,b]) such that ( f(c) = k ).

Differentiability and Continuity

A function that is differentiable is necessarily continuous, establishing a foundational relationship between the two concepts.

Mean Value Theorem for Derivatives

States that if ( f(x) ) is continuous on ([a,b]) and differentiable on ((a,b)), there exists a point ( c ) in ((a,b)) where the instantaneous rate of change ( f'(c) ) equals the average rate of change over the interval, calculated as (\frac{f(b) - f(a)}{b - a}).

Rolle's Theorem

A special case of the Mean Value Theorem which applies when ( f(a) = f(b) ) for a continuous and differentiable function; guarantees at least one point ( c ) in ((a,b)) where ( f'(c) = 0 ).

Extreme Value Theorem

Guarantees that a continuous function defined on a closed interval ([a,b]) will attain both a maximum and minimum value at least once on that interval.

Mean Value Theorem for Integrals

If ( f(x) ) is continuous on ([a,b]), there exists a point ( c ) in ([a,b]) where the function's value at ( c ) equals the average value of the function over the interval, given by the formula ( f(c) = \frac{1}{b - a} \int_a^b f(x)dx ).

Fundamental Theorem of Calculus

Part 1: Relates differentiation and integration, stating that if ( f(x) ) is continuous, then the derivative of the integral function from ( a ) to ( x ) equals the original function: ( \frac{d}{dx} \int_a^x f(t) dt = f(x) ).
Part 2: States that for a continuous function ( f(x) ) over ([a,b]), if ( F(x) ) is an antiderivative of ( f ), then the definite integral from ( a ) to ( b ) can be computed as ( \int_a^b f(x)dx = F(b) - F(a) ). This highlights the total change over the interval.
