Answer:
For we will have positive values only.
Rest are positive so will give positive values out of the modulus function.
Step-by-step explanation:
The absolute value of any number is its positive value only.
As for example and
both are having equal distance from
in a number line, one on the left other on the right side of the number line but are equidistant from
.
So absolute value of a number is its distance on number line from reference point .
One by one we will work with all of our question.
So we have to take the positive number out of the modulus function that is also called absolute value.
