If n ≠ 0, which of the following must be greater than n?
I. n^4
II. 2n
III. 2 - n
Pick one
A) I only	B) II only	C) I and II only	D) II and III only	E) None
n ≠ 0 =&gt; n = negative or n = positive   if n = negative:   2n &lt; n (n = -1 then 2n = -2 =&gt; -2 &lt; -1)   n^2 &gt; n (n =-1 then n^2 = 1 =&gt; n^2 &gt; n)   2 - n &gt; n (n = -1 then 2--1 = 2+1=
