f(x)= x+3/x-3
find: lim f(x) as x approaches 3- for those two I am thinking that the limit does not exist
lim f(x) as x approaches 3+ since the V.A is x=3
lim f(x) as x approaches +infinity, I got 1 but I am not sure
lim f(x) as x approaches -infinity, I got 0, is that right?

Question

f(x)= x+3/x-3
find: lim f(x) as x approaches 3-    for those two I am thinking that the limit does not exist           
        lim f(x) as x approaches 3+    since the V.A is x=3
        lim f(x) as x approaches +infinity, I got 1 but I am not sure 
        lim f(x) as x approaches -infinity, I got 0, is that right?

Hint: Vertical asymptote at x = 3.

yes i know that, thats why I don't understand what the limit would be for 3- and 3+
