Learn how to find the derivative of x^4. The derivative is d/dx[x^4].
Below is the graph of f(x) = x^4 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.
The function x^4 follows a specific power structure, which is exactly what the Power Rule is designed for. This rule applies when a function is in the form f(x) = x^n, where n is a constant exponent.
💡 Why this works: Because x^4 is a power function, we apply the Power Rule, which is designed to handle such expressions. The structure of x^4 fits perfectly into the requirements for using this rule.
The Power Rule states that the derivative of x^n is n * x^(n-1). For x^4, the exponent n is 4. Therefore, applying the rule gives us: d/dx[x^4] = 4 * x^(4-1) = 4x^3.
💡 Why this works: By applying the Power Rule, we reduce the exponent by 1 and multiply by the original exponent, resulting in 4x^3. This is the derivative of x^4.
After applying the Power Rule, the expression simplifies to 4x^3, which is the derivative of x^4. There’s no further simplification required.
💡 Why this works: The result, 4x^3, is the simplest form of the derivative. To verify, you could use a graphing tool or check against known differentiation rules, but this is the correct result from applying the Power Rule.
