Which of the following functions does not intersect with w = 3x^2 + 2x + 1 Select the correct option
A) W = 3x^2 + 3x + 1	B) W = 2x^2 + 3x + 1	C) W = 3x^2 + 2x + 3	D) W = 4x^2 + 2x - 3	E) W = x^2 + 2x + 3
Let’s find the actual intersecting point of given function and each choice w   A. 3x^2 + 2x + 1 = 3x^2 + 3x + 1 --&gt; x=0   B. 3x^2 + 2x + 1 = 2x^2 + 3x + 1 --&gt; x^2 – x =0 --&gt; x=0 or 1   C. 3x^2 + 2x + 1 = 3x^2 + 2x + 3 --&gt; 1=3(X) --&gt; they don’t have any intersect.   D. 3x^2 + 2x + 1 = 4x^2 + 2x - 3 --&gt; x^2 –4=0 --&gt; x= 2 or -2   E. 3x^2 + 2x + 1 = x^2 + 2x + 3 --&gt; 2x^2 –2 =0 --&gt; x= 1 or –1.   So only choice (C) has no intersecting point. The answer is (W = 3x^2 + 2x + 3).
