"WebA function can be one-one and a function can be onto. A function can be one-one and onto both. We can say a function is one-one if every element of a set maps to a unique element of another set. And if codomain of a function and range are exactly the same, then it can be known as onto. " - Function onto and one to one

Is a linear transformation onto or one-to-one?

WebIf you want to show that a function, say f, is 1-to-1, then you typically consider two values x 1, x 2 in the domain of f such that f ( x 1) = f ( x 2). From this, if you can derive that x 1 = x 2, then your function is 1-to-1. Let's consider your first example. We would have f ( x 1) = 4 x 1 + 1 = 4 x 2 + 1 = f ( x 2).
