Answer:
(-∞,3)∪(3,∞)
Explanation:
Division by zero is division where the divisor (denominator) is zero which is indeterminate. Thus the denominator of this equation can not equal to 0, which could express as
x - 3 = 0 which x = 3
This mean at x = 3 the equation will be indeterminate
The domain could be written as (-∞,3)∪(3,∞)
