Questions and Answers

What does the formula for the derivative of a function f(x) represent in terms of the tangent line to the graph of the function?

The formula represents the slope of the tangent line to the graph of f(x) at the point (x, f(x)).

The ______ of a function f(x) at a point x = c is the slope of the tangent line to the graph of f(x) at the point (c, f(c)).

derivative

What is the difference between a function being continuous at a point and differentiable at that same point?

A function is continuous at a point if its graph can be drawn without lifting the pen from the paper. A function is differentiable at a point if it has a tangent line at that point, meaning the function is smooth and not jagged at that point.

If a function has a derivative at a point, then it must be continuous at that point.

What is the chain rule in calculus?

The chain rule is used to find the derivative of a composite function, which is a function that is made up of two or more functions. It states that the derivative of a composite function is the product of the derivative of the outer function and the derivative of the inner function. More explicitly, if y = f(u) and u = g(x), then dy/dx = dy/du * du/dx Signup and view all the answers

What is the product rule in calculus?

The product rule is used to find the derivative of the product of two functions. It states that the derivative of the product of two functions is equal to the first function times the derivative of the second function plus the second function times the derivative of the first function. More explicitly, if y = u(x)v(x), then dy/dx = u'(x)v(x) + u(x)v'(x) Signup and view all the answers

What is the quotient rule in calculus?

The quotient rule used to find the derivative of the quotient of two functions. It states that the derivative of the quotient of two functions is equal to the denominator times the derivative of the numerator minus the numerator times the derivative of the denominator, all divided by the square of the denominator. More explicitly, if y = u(x)/v(x), then dy/dx = (v(x)u'(x) - u(x)v'(x)) / (v(x))^2 Signup and view all the answers

What is the second derivative of a function?

The second derivative of a function is the derivative of its first derivative. It measures the rate of change of the first derivative, which in turn represents the rate of change of the original function. Signup and view all the answers

What are higher-order derivatives in calculus?

Higher-order derivatives are derivatives of derivatives. They are obtained by repeatedly differentiating a function. For example, the third derivative is the derivative of the second derivative, the fourth derivative is the derivative of the third derivative, and so on. Signup and view all the answers
