If the function \(g\) is deﬁned for all nonzero numbers \(y\) by \(g(y)=\frac{y}{|y|}\), find the value of each of the following.
(a) \(g(2)\)
(b) \(g(-2)\)
(c) \(g(2) -g(-2)\)
(a) \(g(2)=\frac{2}{|2|}=\frac{2}{2}=1\)
(b) \(g(-2)=\frac{-2}{|-2|}=\frac{-2}{2}=-1\)
(c) \(g(2) - g(-2) = 1 - (-1) = 2\)
