Hi. I was wondering if you could help me solve this. I've tried drawing it but it doesn't work, and anyway, I want to be able to solve it in a more elegant manner.
I would consider the smallest end-points in magnitude from the origin for each value of m.
The smallest in the negative is -1 and the smallest on the positive side is unbounded (since n/m -> infinity).
So with this you are going to have (-1,infinity) intuitively with the above reasoning (which may be wrong and if it is please point it out).
