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