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 :)
