Example of Derivative Calculation

Let’s understand how the calculator works with a practical example.

Example Problem

Function:

$f(x) = x^2 + 3x$ f(x)=x2+3x

Value of x:

$x = 2$ x=2

Calculation Results

Function Value:

$f(2) = 2^2 + 3(2)$ f(2)=22+3(2)

$= 4 + 6 = 10$ =4+6=10

Derivative:

The derivative of:

$f(x) = x^2 + 3x$ f(x)=x2+3x

is:

$f'(x) = 2x + 3$ f′(x)=2x+3

At $x = 2$ x=2:

$f'(2) = 2(2) + 3 = 7$ f′(2)=2(2)+3=7

Final Output

f(x): 10
f'(x): 7
Slope at x: 7

This shows that the curve has a slope of 7 at $x = 2$ x=2.

Understanding Derivatives in Simple Terms

A derivative measures how quickly a function changes.

For example:

If the derivative is positive, the function is increasing.
If the derivative is negative, the function is decreasing.
If the derivative is zero, the graph may have a maximum or minimum point.

The derivative is also known as:

Instantaneous rate of change
Gradient
Slope of the tangent line
