T do not know what you are already supposed to know, and/or how you are expected to solve the problem, but maybe some of what follows will sound familiar.
The equation represents and graphs as a hyperbola,
a set of two curves that look like an inverted set of brackets,
like a corset fastened around the origin, looking like this )+( .
For the points on those curves, .
The points in between those curves have smaller values that the points directly to their left and right on the hyperbola,
so for those points, .
The points on the outside of the hyperbola have larger values that the points at the same height (same ) on the hyperbola,
so for those points, .
I would graph the hyperbola as dashed lines and would color the space outside the two curves, like this:

Maybe you are expected to make a table of (x,y) value pairs, plot the points and join them with two curves.
Maybe you know about hyperbolas, their asymptotes and vertices, and that will allow you to draw a better hyperbola.
