hi try using: then use substitution. hope this helps.
We've got to find a set of points (x,y) (and mark it on a plane) which satisfies this inequality.That's all.

you cannot multiply because you don't know if the sign of the denominator is + or -. did you try using substitution?it will make it a little easier to see what you can do.
I don't know what should I substitute, some clue?
try
so -1<t<0 or t>1?
that's pretty much right. what do you get when you sub?
rewrite by meaning: x^a = (y-2); (y -2)^(1/a) = x is same as: a > 1/a solve for a
or and how can I determine x and y?

Here is a plot (starting from 100,000 random points), both axes are [-5,5].
