1. ## Test question: Function

Could someone explain to me this:

if the function g is defined for all nonzero numbers y by
$g(y)=\frac{y}{|y|}$
what is the value of $g(2)-g(-200)$ ?

Thank you!

Thank you!
$g(2) = \frac{2}{|2|} = \frac{2}{2} = 1$.

$g(-200) = \frac{-200}{|-200|} = \frac{-200}{200} = -1$.

3. ## Thanks!!!

Thank you! I'm ashamed, it was very simple!!
