👉 In mathematics, a pertish is defined as an object that is not at all like anything it was before. It can be seen as a representation of a mathematical concept or idea that has been altered or distorted by the application of a specific operation or formula. For example, consider the function f(x) = x^2 - 3x + 4, which represents the graph of a quadratic equation in two variables. The graph of this function is not exactly the same as the original one.
