Mode function
It can never be negative.
Given
[tex]f(x) = \left|x \right|[/tex]
How to solve it?
a. The mode function can never be negative.
[tex]f(x) = \left|x \right| [x\geq 0,\ f(x) = x]\\f(x) = \left|x \right| [x< 0,\ f(x) = -x][/tex]
b. Put any real value of x, we will get always a positive term.
If we put a negative number our function is defined as
[tex]f(x) = \left|x \right| [x< 0,\ f(x) = -x][/tex]
If we put a positive number our function is defined as
[tex]f(x) = \left|x \right| [x\geq 0,\ f(x) = x][/tex]
So, put any real value of x, we will get always a positive number or value.
