How can I "easily" solve or understand the application of derivative involving the rate of change?

Is there a general explantion for these kinds of problem?
In numbers, if f is the function, we want to know what happens in
{f(x+e)-f(x)}/e
as e gets small.
A derivative is a mathematical concept that describes the rate of change of a function with respect to its input. It represents the slope of a tangent line to a curve at a specific point.
The derivative is important because it allows us to understand the behavior of a function and make predictions about its values. It is also necessary for solving optimization problems and understanding rates of change in real-world situations.
The derivative of a function is calculated using a mathematical formula called the limit definition of a derivative. This involves taking the limit of a difference quotient as the change in input approaches zero.
The derivative represents the instantaneous rate of change of the original function at a specific point. It is also related to the slope of the tangent line to the function at that point. The derivative and the original function are intimately connected and can be used to find information about each other.
The derivative has many real-life applications, such as predicting the growth of populations, analyzing stock market trends, and determining the optimal route for a car to take. It is also used in physics and engineering to understand rates of change in physical systems.
