The derivative of a function represents the rate at which the function changes at each point. It is defined as the limit of the difference quotient as the distance between two points on the function approaches zero. The derivative of a function f(x) with respect to x is denoted as f'(x) or df/dx.
The formula for the derivative of a function f(x) is given by:
f'(x) = lim(h->0) [f(x+h) – f(x)]/h
This formula represents the change in f(x) for a small change in x (h). The limit as h approaches zero represents the instantaneous rate of change of f(x) at a given point x.
The derivative can also be found using the power rule, product rule, quotient rule, or chain rule, depending on the form of the function. Each rule provides a shortcut method for finding the derivative of a function without having to use the definition of the limit.
Overall, the derivative of a function is an important concept in calculus and is used in many areas of mathematics, physics, engineering, and other sciences.

Case Study on Derivative of a function
Case Study: Finding the Derivative of a Polynomial Function
Let’s consider the function f(x) = 3x^2 – 2x + 1. We want to find the derivative of this function, which represents the rate of change of the function with respect to x.
To find the derivative of f(x), we can use the power rule of differentiation, which states that if f(x) = x^n, then f'(x) = nx^(n-1). Using this rule, we can find the derivative of each term in f(x) separately and add them up to get the derivative of the whole function.
So, let’s find the derivative of each term in f(x):
f'(x) = d/dx [3x^2] – d/dx [2x] + d/dx [1]
Using the power rule, we have:
f'(x) = 6x – 2
Therefore, the derivative of f(x) is f'(x) = 6x – 2.
Now, we can use this derivative to analyze the behavior of the function f(x). For example, we can find the critical points of the function, which are the points where the derivative is zero or undefined.
Setting the derivative equal to zero, we get:
6x – 2 = 0
Solving for x, we have:
x = 1/3
Therefore, the critical point of the function is x = 1/3.
We can also find the interval where the function is increasing or decreasing by analyzing the sign of the derivative. If f'(x) > 0, then f(x) is increasing, and if f'(x) < 0, then f(x) is decreasing.
Since f'(x) = 6x – 2, we can see that f'(x) > 0 when x > 1/3, which means that f(x) is increasing on the interval (1/3, infinity). Similarly, f'(x) < 0 when x < 1/3, which means that f(x) is decreasing on the interval (-infinity, 1/3).
In conclusion, the derivative of a polynomial function can be found using the power rule of differentiation, and it provides important information about the behavior of the function such as critical points and intervals of increase or decrease. The techniques of differential calculus, including finding derivatives, are widely used in many fields, including physics, engineering, economics, and more.
