Assuming [x] means the closest integer to x

Answer:


(-\infty, \infty)

Explanation:

We can see that for any integer
x, there will always be a
[x], so there will always be a
[x]+1. So, we don't need to worry about the domain impacting the range.


[x] can be any integer from
-\infty to
\infty, and as
\infty+1=\infty(at least in terms of a function's range and domain), the range of
[x]+1 is equal to the range of
[x], which is
(-\infty, \infty).

So, the answer is
\boxed{(-\infty, \infty)} and we're done!
