1. The problem is to find the derivative of a function, but the function is not specified in the question. 2. To find the derivative of a function $f(x)$, we use the definition of the derivative or known differentiation rules such as the power rule, product rule, quotient rule, or chain rule. 3. Since the function is not given, please provide the function expression to proceed with finding its derivative. 4. Once the function is provided, I will show step-by-step how to differentiate it and explain the rules used. Please provide the function to differentiate.
