The question requests the continuous intervals, so you could just look for runs of curve that's connected and then figure out the end points. The first of these intervals are [-4, 2) (-2, 2) See if you can do the rest.

[4, 6) (6, 8] is it right?

They are almost right, only the end points are wrong. You can see that at x=4 we have a singularity (which means it blows up to infinity), so the function is not defined there. That means x=4 it can't be included in any interval, so instead of [4, 6) it's (4, 6). For (6, 8] it looks like there is an un-filled circle at x=8, which means that it's not in the interval either so it should be (6, 8). You also missed an interval at [2, 4). Hope this helps!
