👉 In mathematics, a flatness property is a mathematical condition that describes how a function behaves when evaluated at points of zero or more than one dimensional space. A function is said to be "flat" if it has no singularities in its domain. For example, consider the function f(x) = x^2 - 3x + 2. In this case, the domain of f is all real numbers (considering x as a variable). The function f is not defined at any point
