👉 In mathematical terms, a function is said to be monotonous if it either increases or decreases without bound. This means that for any two points in its domain, the value of the function at those points will always increase or decrease by the same amount, respectively. For example: - f(x) = x^2 - 4x + 3 - g(x) = (x+5)/2 In this case, both functions are monotonous because they either increase or
