Let's ignore this negative for the time being. That negative's out front. This numerator, this one, is always going to be positive. Down here, we're taking the, at x equals one, well, this becomes zero, and the whole expression becomes undefined, but as we approach one, x minus one could be positive or negative, as we see over here, but then when we square it, this is going to become positive as well. So the denominator's going to be positive for any x other than one, so positive divided by positive is going to be positive, but then you have a negative out front. So this thing is going to be negative for any x other than one, and it's actually not defined at x equals one. And so you could, from that, you could deduce, well, okay, then we can only go to negative infinity.
