In order to find the limit at x -> 5, we need to check the limit from the left and from the right of 5.
Looking from the left of 5 (that is, x -> 5-), we can see that the function approaches negative infinity.
Looking from the right of 5 (that is, x -> 5+), we can see that the function approaches positive infinity.
Since the limits from the left and right are different, so the limit for x -> 5 is unbounded.
