Finding the domain of

G(X)=4/4-3X

Unsure where to begin here

g(x) is like a y. What x values could one or could one not insert to get a y value out? Domain is like x and range is like y. x could not be 4/3 because 4/3 times 3/1 equals 4 and 4-4=0 and one can not definitively divide anything by zero.
