👉 In mathematics, an "outfangthief" is a type of function that has only one value for any given input. This means that no matter what the input is, the output will always be exactly that value. For example, the function f(x) = x^2 - 1 over the interval [0, 3] would give the same output as the function g(x) = sin(x) over the interval [-π/2, π/2].
