Let's get some definitions first.
Whole numbers : 0,1,2,3,4,...
Integers : Whole numbers and negative whole numbers : ...,-4,-3,-2,-1,0,1,2,3,4,...
Rational numbers : Numbers defined as ratios of integers : 1/2, 5/6, 8/3,...
When x=-1
1/2 is a rational number
When x=0
-1/3 is a rational number
When x=1
1 is a rational number (1/1), an integer, and a whole number
