01 Solve each problem and check your answer.

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

1. For r(x) = (x² − 1)/(x + 1), state the x-value of the hole.

2. For r(x) = (x² − 4)/(x − 2), state the x-value of the hole.

3. For r(x) = (x² − 4)/(x + 2), state the x-value of the hole.

4. For r(x) = (x² − 1)/(x − 1), state the x-value of the hole.

5. For r(x) = (x² − 9)/(x + 3), state the x-value of the hole.

6. For r(x) = (x² − 0)/(x + 0), state the x-value of the hole.
