Question 1120784
<font face="Times New Roman" size="+2">


I'm not sure that I know how to "find" the functions other than the following trivialities:  Google translate to Portugese: Não tenho certeza se sei "encontrar" outras funções além das seguintes trivialidades:



*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f\ +\ g\ =\ |x|\ +\ \lfloor{x}\rfloor]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f\ -\ g\ =\ |x|\ -\ \lfloor{x}\rfloor]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f\ *\ g\ =\ |x|\ *\ \lfloor{x}\rfloor]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ \frac{f}{g}\ =\ \frac{|x|}{\lfloor{x}\rfloor}]


*[illustration absPlusfloor].
f + g


*[illustration absMinusfloor]
f - g


*[illustration absXfloor.jpg]
f * g


 *[illustration absOverFloor.jpg]
f / g

My calculator said it, I believe it, that settles it
