The domain of a function is all the values a function can have along the x-axis and is defined, and the range is all the values a function can take placed for all x that define the function.
According to this we can see there is an asymptote at x=1, meaning that the function is not defined at this value and the domain will be all numbers different to x=1.
[tex](-\infty,1)\cup(1,\infty)[/tex]As for the range the function can take all numbers along the y axis which means that the range is
[tex](-\infty,\infty)[/tex]
