If x > y^2 > z^4, which of the following statements could be true?
I. x > y > z
II. z > y > x
III. x > z > y
I. x > y > z
II. z > y > x
III. x > z > y
If we CAN find a set of values for x, y and z that satisfies a statement AND yields values such that x > y^2 > z^4, then we'll KEEP that statement.If x > y^2 > z^4, which of the following statements could be true?
I.x > y > z
II. z > y > x
III. x > z > y
A. I only
B. I and II only
C. I and III only
D. II and III only
E. I, II and III
Statement I. x > y > z
If x = 2, y = 1, and z = 0, then x > y^2 > z^4
KEEP statement I
Statement II. z > y > x
If x = 1/4, y = 1/3, and z = 1/2, then x > y^2 > z^4
KEEP statement II
Statement III. x > z > y
If x = 2, y = -1, and z = 0, then x > y^2 > z^4
KEEP statement III
Answer: E
