Modulus Function is the function in which the image of domain's any real number is the positive real counter part in the co domain...
It's Algebraically defined as
f(x) = |x| or
f(x) = { x , if x>=0 & -(x) , if x<0 }

Range(f) = Real No. (- <><>,+ <><>)
Domain(f) = Positive Real No. [0 , +<><>)

The graph of the modulus function is given below.
