👉 "Bound" is a mathematical concept that refers to something being within certain limits or constraints. It can be used in various fields such as mathematics, physics, engineering, and computer science. In physics, bound refers to the limit of a function at a specific point. For example, if you have a function f(x) = x^2 - 4x + 3, and you want to find the bound of this function at x=1, then the bound would be 0 because
