Answer:
D) |x| = a and |y| = b
Step-by-step explanation:
Given the numbers x = a and y = –b
Absolute function always gives the output as a positive number
Absolute function of |-x|= x
For example |5|= 5 and |-5| = 5
Given x=a
|x| = |a| = a, so |x| = a
Given y=-b
|y| = |-b| = b , so |y| = b
Hence, |x| = a and |y| = b
