Use the function rule and give an exact answer where possible.

1. For f(x) = 1/(x + 3), state the excluded x-value.

2. For f(x) = 1/(x + 0), state the excluded x-value.

3. For f(x) = 1/(x − 3), state the excluded x-value.

4. For f(x) = 1/(x + 1), state the excluded x-value.

5. For f(x) = 1/(x − 2), state the excluded x-value.

6. For f(x) = 1/(x + 2), state the excluded x-value.
