A) I only	B) III only	C) I and II	D) I and III	E) II and III
I. 2x - 5 --&gt; x decreases from 169 to 166 --&gt; 2x decreases --&gt; 2x - 5 decreases.   II. 1 - 1/x --&gt; x decreases from 169 to 166 --&gt; 1/x increases --&gt; 1 -1/x decreases.   III. 1/(x^2 - x) --&gt; x decreases from 169 to 166 --&gt; x^2-x decreases --&gt; 1/(x^2 - x) increases.   Answer: III only.
