Chapter 1 - Functions and Limits - 1.5 The Limit of a Function - 1.5 Exercises - Page 61: 33

$\lim\limits_{x \to 1}$ $\frac{2-x}{(x-1)^{2}}=\infty $

The numerator is positive for $x<2$, and as the denominator is positive for all $x$. Since as $x$ tends to one the denominator tends to $0$, the limit is positive infinity.
