👉 The derivative of a function is defined as the slope of the tangent line to the graph of the function at any given point. It represents the rate of change or how much the output variable changes for every unit increase in the input variable. For example, if we have a function f(x) = x^2 - 3x + 4 and we want to find its derivative, we would take the derivative of this function with respect to x. This means taking the first derivative (which is
