Find the domain of -2(-x+3) / 4(-2x)
-
This is a rational function ... i.e. a fraction.
Since you cannot divide by 0, the only numbers that cannot be in the domain are the numbers that make the denominator 0.
For -2(-x+3) / 4(-2x), Assuming that the denominator is 4(-2x), the only number that makes it zero is x=0.
So, the domain is all numbers except 0.
Domain = {all real numbers except 0} ← ANSWER
