Question Description
A function is one-to-one if any two different inputs in the domain correspond to two different outputs in the range. That is, if x1 and x2 are two different inputs of a function, f, the f is one-to-one if f(x1)≠ f(x2) . A function is not one-to-one if two different inputs correspond to the same output. If a function is one-to-one, it has an inverse.
Create real-life example of a function that is one-to-one and a real-life example of a function that is not one-to-one.
