Question 23:

Column AColumn B

x2 + 1x + 1

(a) The quantity in Column A is greater then the quantity in Column B.

(b) The quantity in Column B is greater then the quantity in Column A.

(c) The two quantities are equal.

(d) The relationship cannot be determined from the information given.

Answer: We need to compare x2 + 1 with x + 1. This results in a comparison between x2 and x.

For some x, x2 will be greater than x, e.g. for x = 2. For others, e.g. x = 1/2, x2 will be lower so the relationship cannot be determined from the information given.
