Is the following correct.(adsbygoogle = window.adsbygoogle || []).push({});

1. f(x) is a function if for every x value there is exactly one y value. so sin x is a function.

2. does a 1-1 function mean that the line y = constant cut the graph in exactly one place? therefore sin (x) is not a 1:1 function but is still a function?
