👉 In mathematics, a superrationally function is a function that has both an infinite limit and an infinite limit at infinity. This means that for any given real number x, there exists some positive real number R such that if x approaches +โ, then f(x) approaches R; but if x approaches -โ, then f(x) also approaches R. For example, the function f(x) = 1/x^2 is a superrationally function because as x becomes very large, f
