WebWe say that a function is one-to-one if, for every point y in the range of the function, there is only one value of x such that y = f (x). f (x) = x 2 is not one to one because, for example, there are two values of x such that f (x) = 4 (namely –2 and 2). On a graph, a function is one to one if any horizontal line cuts the graph only once.

WebHence it looks like f ( x) = x 2 − 2 is a good candidate. Of course, x + 1 x ≥ 2 implies that we cannot say anything about f ( x) if x < 2 . But for x ≥ 2, we can find a real number t such that t 2 − x t + 1 = 0 (and hence t + 1 t = x ), namely t = x ± x 2 − 4 2, and then see that indeed f ( x) = f ( t + 1 t) = t 2 + 1 t 2 = x 2 − 2.
