If u > 0, which of the following could be true?
I. u^3 > u^2
II. u^2 = u
III. u^2 > u^3 Pick one.
A) I only	B) III	C) IIIII	D) All of the above	E) None of the above
1. u^3 &gt; u^2 Well this is true for all u &gt; +1 (but not for values 0 &lt; u &lt; 1)   2. u^2 = u This is true for only one positive number, 1   3. u^2 &gt; u^3 Again this is true only for values of u such that 0 &lt; u &lt; 1   So the answer is All of the above, since there exists at least one value of u which satisfies the equation/ in equation(s)
