👉 In a mathematical context, "growthiness" refers to a property of a function or a sequence that indicates how quickly it grows or decreases over time. This property is often used in optimization problems where we are trying to find the best solution for some objective function subject to constraints on its parameters. For example, consider a simple function g(x) = x^2 - 3x + 4. We can calculate its derivative (the rate of change at any point) as follows: d(g
