I know how to find domains, but this instruction on the method to do it with confused me. I remember my teacher doing a long series of + and - symbols placed vertically below a number line, but I'm not sure how she did it. The problem I am supposed to find the domain of is:
2x X > 3X
_____ + _ _________
2 2 2
X -4 X +X-6 X + 5X + 6
Any help would be appreciated. Thanks.
