Answer:

The only domain restriction is that #x!=-4#

Explanation:

This would make the numerator #=0# (not allowed)

As #x# grows larger, the #-2and+4# make less difference, so the function will get closer and closer to #x/x=1#, without reaching it.
So range is restricted to #F(x)!=1#
graph{(x-2)/(x+4) [-36.55, 36.55, -18.25, 18.26]}
