Answer:
-2: in domain
0: in domain
3: not in domain
Step-by-step explanation:
First, understand that the numerator cannot be 0:
(for example, can you find 0/7? How about 0/3?)
Therefore, the x-value that makes the numerator equal to zero makes the function unsolvable:
x-3=0
x=3
So, 3 cannot be in domain.
The denominator can be 0, so -2 can be in domain.
0 does not make the numerator to 0, so zero can be in domain.
I hope this helps :)
