Limit of (x-1)/(1-x) as x approaches negative infinity

[meeklobraca]

Homework Statement

lim x-1/1-x
x-->-infinity

Homework Equations

none really

The Attempt at a Solution

Other questions relating to this part of limits have us factor out the x from the function. So when I take the x out of the function I get 1/-1 with a final answer of -1.

Is this correct?

You don't "take x out of the function." You note that the constant 1 and -1 are not relevant when x is very large. The equation reduced to x/-x = -1. There's your limit.
