Answer by nerdybill(7384)   (Show Source):
You can put this solution on YOUR website! Domain defines the range of numbers 'x' can take.
.
Remember, if the denominator is ZERO, the fraction is undefined!
.
Therefore, the ONLY value x CAN'T take is it it makes the denominator 0.
.
Setting the denominator to 0, we can solve for x:
3x = 0
x = 0
.
Therefore, the "domain" is ALL real numbers EXCEPT 0.
