The absolute value of 19 is 19. If x is positive , absolute x equals x.
|x| = 1.286

x= -1
What is the domain and range of absolute lxl - 5
4
If: x4 = 5 Then: x = 1.4953487812
x= -6
When 'x' and 'y' both have the same sign.

That is how the absolute value is defined. For x < 0 the value of x is negative (by definition). Therefore, the value of negative x is positive (negative of a negative). So abs(x) = -x when x < 0
