Expert Answer
Answer : The absolute value (or modulus) |?a?| of a real number a is the numerical value of "a" without regard to its sign. So, for example, the absolute value of 3 is 3, and the absolute value of 3 is also 3.
That is we can say that
f(x)= { -x , x < 0
0 , x = 0
x , x > 0
}
That is for whatever value of x we take from -infinity to + infinity, the value is a positive quantity always.
