If x is a number such that -2=<x<=2, which of the folloing has the greatest possible absolute value?
A). 3x-1
B). x^2+1
C). 3-x
D). x-3
E). x^2-x
A). 3x-1
B). x^2+1
C). 3-x
D). x-3
E). x^2-x
Option [spoiler]A)3x-1[/spoiler]
a) |3x-1| = 7 when x=-2 and =5 when x=2
b) |x^2+1| = 5 when x=-2 or 2
c) |3-x| = 5 when x=-2 and =1 when x =2
d) |x-3| = 5 when x=-2 and =1 when x =2
e) |x^2-x| = 6 when x=-2 and =2 when x =2
