SOLUTION: ok...
i just need to know.
if i have this problem
f(5m) if f(x)=|x^2 - 13|
i know that the x turms to 5m but when i remove the absolute value would the - 13 become + ?

You can put this solution on YOUR website! f(5m) if f(x)=|x^2 - 13|
i know that the x turms to 5m but when i remove the absolute value would the - 13 become + ?
----------
f(5m) = |25m^2 - 13|
If 25m^2-13 is <0, then it is multiplied by -1 to make it positive.
If it's >=0, then it's left as it is.
-------------
There's no way to know which case if the value of m is not known.
