frac() is the fractional part function.

## Homework Equations

## The Attempt at a Solution

I tried it by graphing.

Firstly i drew the graph of frac(x) and then frac(-x). I added them. The resulting graph was constant at 1 but discontinuous at integers. So the answer to the question is 1 but wolfram gave me the answer to be 0. :(

I don't understand where i am wrong?
