Learn how to find the derivative of x^n. The derivative is d/dx[x^n].
Below is the graph of f(x) = x^n and its derivative f'(x). Notice how the original function and derivative relate to each other.
Original Function:
Derivative:
This derivative represents the rate of change of the original function. The calculation follows standard differentiation rules as shown in the step-by-step solution below.
To differentiate x^n, we recognize that it is a power function. The Power Rule applies because x is raised to a constant power n.
💡 Why this works: The Power Rule is used for functions of the form x^n, where n is a constant. This structure allows us to apply the rule directly, which simplifies the differentiation process.
Now, we apply the Power Rule to differentiate x^n. According to the Power Rule, we multiply the exponent n by the coefficient (which is 1) and then subtract 1 from the exponent.
💡 Why this works: Applying the Power Rule, we get the derivative f'(x) = n * x^(n-1). This results from multiplying the original exponent by the function’s coefficient and lowering the exponent by 1.
The expression simplifies directly to the final derivative form, n * x^(n-1). This is the derivative of x^n.
💡 Why this works: By simplifying the expression, we confirm that the derivative of x^n is correctly represented as f'(x) = n * x^(n-1), which describes how the function changes with respect to x.
