We have
For the domain are all the possible values of x that the function can use as we can see the domain are all the number from minus infinity to infinity except -3
[tex]-\infty
For the range are all the possible values of the function in other words all the possible values in the y-axes we can see it is
[tex]1
we have different intervals of continuty
[tex]-\inftyand we have two discontinuities one in -3 and the other one in 3 it can see it in the graph as the unfilled circles.
x=-3
x=3
