f(x)   =  3x - 7

            ______

              x +  1

We have  vertical  asymptote at  x = -1      and a horizontal asymptote at  y =  3

So......when x  < -1      y  is  >  3

And when  x  > -1       y is < 3

So....the range  is   ( -infinity , 3)  U (3 , inf)

Here is a graph : https://www.desmos.com/calculator/r9bpootve2

Thanks again!
