II. 1/(2x^2 − x)
III. (x + 1)
Choose the correct choice from the following answers
A) I only	B) II only	C) III only	D) I and II only	E) II and III only
let x= 4 and 3 b old and new values   ST1: x= 4 -&gt; 4+16 = 1/20   x=3-&gt; 3+9 = 1/12 ...increased   ST2:x= 4-&gt; 2*16-4 =1/ 28   x=3-&gt;2*9-3 = 1/15   Increased   St3: x=4-&gt; 5   x=3-&gt;4   Ans: III only
