The Formula for a Derivative. To show how to find the derivative of a function that is defined by a formula, consider the function. y = f(x) = 3x 2 – 5. To find the derivative of this function at some particular point (for example, x = 2), first find the average rate of change in the interval from x = 2 to x = 2 + Δx.
