Finding the derivative of a function from first principles, also known as the limit definition of a derivative, is a fundamental concept in calculus 😊. Given a function f(x), the derivative f'(x) represents the rate of change of the function with respect to x. To find f'(x) from first principles, we use the limit definition: f'(x) = lim(h → 0) [f(x h) - f(x)]/h Here's a step-by-step process: 1. Start with the function: Begin with the given function f(x). 2. Apply the definition: Write the limit
