👉 In mathematics, monotonicity is a property of functions that ensures their behavior remains constant over an interval or domain. It means that for any two points in the domain, as one moves away from the other, the value of the function remains the same. For example: - A function that increases without bound (monotone increasing) would be defined by a sequence of values where each term is greater than the previous term. - A function that decreases without bound (monotone decreasing) would
