Question

List L consists of numbers 1, square root of 2, x, and x^2 , where x>0, and the range of the numbers in list L is 4.

Which quantity is larger?
A. x
B. 2

Answer 1

Since the range is 4 and x^2 > x, this means that x^2 - 1 = 4


Solve this for x to get x = sqrt(5) which is approximately 2.24


So x is the larger quantity

Answer 2

Note: since x > 0, we know that x^2 > x
