The power function is a mathematical function of the form f(x) = ax^b, where a and b are constants.
To derive the power function, we start with the general form of a function:
f(x) = ax^b
To find the derivative of this function, we use the power rule of differentiation. According to the power rule, the derivative of x^n with respect to x is nx^(n-1), where n is any real number.
Applying the power rule to the function f(x) = ax^b, we have:
f'(x) = d/dx(ax^b) = abx^(b-1)
Therefore, the derivative of the power function f(x) = ax^b is f'(x) = abx^(b-1).
