7.1: Funciones uno a uno
Hemos visto que algunas funciones f pueden tener las mismas salidas para diferentes entradas. Por ejemplo para f (x) =x², las entradas x=2 y x=−2 tienen la misma salida f (2) =4 y f (−2) =4. Una función es uno a uno, precisamente cuando no es así.
7.2: Función inversa
Una función es uno a uno, cuando cada salida está determinada por exactamente una entrada. Por lo tanto, podemos construir una nueva función, llamada función inversa, donde invertimos los roles de entradas y salidas.
