WebBasically, if you draw a vertical line through any given part of the graph of the function, the vertical line will cross the graph of the function in at most one place. It is possible it will not cross the graph at any point depending on the function, but for linear functions, the vertical line will cross the graph at one point only (except for ... WebWhile all linear equations produce straight lines when graphed, not all linear equations produce linear functions. In order to be a linear function, a graph must be both linear (a straight line) and a function (matching each x -value to only one y -value).

WebSep 24, 2024 · Let's say we have a function, y = 2 x. We know this is a bijection. x = y 2, for every y ∈ R we have an x so we have surjection. Then for f ( x 1) = f ( x 2) we come to the conclusion that x 1 = x 2 so it is also an injection. So it is a bijection. I have no problem understanding this. The problem is when I think about it in real numbers.

WebLinear means something that makes a line (pretty simple,) and a function is a set of coordinates or points on a graph that have only one x value to every y value. So basically, a linear function does not curve, but goes in a strait line on a graph. If it curves, this is called a non-linear function. I hope this helped!

By this definition, the constant function f ( x) = b is a linear function. However, we also have the notion of a linear transformation of a vector space, which is essentially something obeying. f ( a x → + b y →) = a f ( x →) + b ...
