👉 Continuity is a fundamental concept in mathematics and physics that refers to the property of a function or another object where its values remain unchanged after any finite number of applications. In other words, if we apply an operation to a function f(x) repeatedly, the value of f(x) will not change. For example, consider the function f(x) = x^2 + 1. If we apply this function four times, the output will be: f(0) = (0)^2
