-4 < x 2

Answer 8

Answer 10

Then we should show that:
-4 <x < 2

Answer 11

Now about those dots. What does the closed dot on -4 mean?

Answer 13

So we need to include the -4 by putting in the equal to part:\[-4\le x < 2\]

Answer 14

And since the dot on the 2 is open, it is not included and we are done.
