The instantaneous rate of change is a concept in calculus that describes how quickly a function is changing at a specific point. It measures the rate at which the dependent variable of a function is changing with respect to the independent variable, at a particular value of the independent variable.

In mathematical terms, the instantaneous rate of change of a function f(x) at a point x=a can be found by taking the derivative of the function and evaluating it at that specific point, which is denoted as f'(a). The derivative of a function represents the slope of the tangent line to the graph of the function at a given point.

To calculate the instantaneous rate of change, follow these steps:

1. Find the derivative of the function f(x) using differentiation rules for the specific type of function you are working with (e.g. power rule, product rule, chain rule, etc.).

2. After taking the derivative, you would have another function representing the slope of the tangent line at any given point.

3. Evaluate this derivative function at a specific point x=a by substituting the value a into the derivative function. This will give you the slope of the tangent line at that point.

The result, f'(a), represents the instantaneous rate of change of the function f(x) at the point x=a. It indicates how quickly the function is changing at that specific point.

It’s important to note that the instantaneous rate of change can vary at different points along the graph of a function, as the slope of the tangent line can be different at different points. The concept of the instantaneous rate of change is essential in understanding topics such as velocity, acceleration, and optimization in calculus.
