Could someone explain to me this: if the function g is defined for all nonzero numbers y by $\displaystyle g(y)=\frac{y}{|y|}$ what is the value of $\displaystyle g(2)-g(-200)$ ? Thank you!

Thank you! $\displaystyle g(2) = \frac{2}{|2|} = \frac{2}{2} = 1$. $\displaystyle g(-200) = \frac{-200}{|-200|} = \frac{-200}{200} = -1$.
Thank you! I'm ashamed, it was very simple!!
