What is a one to one function plus examples?

See the related link - Math Warehouse.First it has to be a function, that means for each and every x value, there is one and only one y value. Often the term vertical line test, is used. That means a vertical line will cross the graph only one time at every x value, then it is a function.If it is a function, and for every y-value, there is only one x-value, then it is a one-to-one function. Often you may see horizontal line test, as a way of checking.Examples of one-to-one functions:y = xy = 2x +3y = e^xExamples of functions, which are notone-to-one:y = x² [parabola: (2)² and (-2)² both equal 4]y = sin(x) [y will oscillate back and forth between +1 and -1 indefinitely]If a function passes the tests and is a one-to-one, then the function will have an inverse.Also, a function can be defined as one-to-one over a specific range. Like x² for all x > 0 {positive numbers}

It really has no function. Since it can rupture when you do ordinary everyday things and you spend the major part of your life without it, we know it's not for protection. If unbroken some see it as a sign that the girl has not been penetrated but that is not a function nature would bother with.
