math
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.

algebra
Take away 8 and 3x=3x+2. Take away 3x and 0x= 0x+ 2 Take anything times zero and you get zero back, so 0=0+2 Zero does not equal 2, so there is no way to do this. 0x=2 Division by zero is undefined.
