01 Substitute the input value into each linear function and simplify.

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

1. If f(x) = 6x + 0, find f(-2).

2. If f(x) = 1x − 2, find f(1).

3. If f(x) = 2x + 3, find f(-3).

4. If f(x) = 3x + 1, find f(0).

5. If f(x) = 4x − 1, find f(3).

6. If f(x) = 5x − 3, find f(-1).

7. If f(x) = 6x + 2, find f(2).

8. If f(x) = 1x + 0, find f(-2).
