And I think you get the idea when someone says one-to-one. Well, if two x's here get mapped to the same y, or three get mapped to the same y, this would mean that we're not dealing with an injective or a one-to-one function. So that's all it means. Let me draw another example here. Let's actually go back to this example right here.Examples of Linear Transformations. Effects on the Basis. See Also. Types of Linear Transformations.
