Q. Find the derivative of f(x).f(x)=x4Write your answer as a constant times a power of x.f′(x)=Submit
Identify Power of x: Rewrite the function in its current form to identify the power of x. The function is already given as f(x)=x4, which is a power function where the base is x and the exponent is 4.
Apply Power Rule: Apply the power rule for differentiation, which states that the derivative of xn is n∗x(n−1). Here, n is 4, so we multiply 4 by x raised to the power of 4−1.
Perform Calculation: Perform the calculation for the exponent. Subtracting 1 from 4 gives us 3, so the new exponent for x is 3.
Write Down Derivative: Write down the derivative. The derivative of f(x)=x4 is f′(x)=4x3.
