## Main Question or Discussion Point

Hi, i have this function [itex]f : x \in Q \rightarrow (5x-7)/6 [/itex]

the function is bijective now i need to calculate:

[itex]f(N0)[/itex]

i get :

[itex]f(0)=-7/6[/itex], [itex]f(1)=-1/3[/itex], [itex]f(2)=1/2[/itex], [itex]f(3)=4/3[/itex], etc...

I need to generalize the set that include the image of [itex]f(N0)[/itex],

but i don't know what could be.
