A One-to-One Function

Now, let's talk about one-to-one functions. A one-to-one function is a function in which the answers never repeat. A normal function can have two different input values that produce the same answer, but a one-to-one function does not. For example, the function f(x) = x^2 is not a one-to-one function because it produces 4 as the answer when you input both a 2 and a -2, but the function f(x) = x - 3 is a one-to-one function because it produces a different answer for every input
