To find the n-th derivative of f, we can use the formula for the n-th derivative of a function. We can start by finding the first derivative of f, then the second derivative, and so on, until we reach the n-th derivative. Each time we take a derivative, we decrease the exponent of the function by 1 and multiply by the original exponent. After n iterations, we will have the n-th derivative of f. **
