Complete the following for the given f(x).

(a) Find f(x + h).

(b) Find the difference quotient off and simplify.

1. f(x) = 3

2. f(x) = 5

3. f(x) = 2x

4. f(x) = 10x

5. f(x) = 2x + 1

6. f(x) = 3x + 4

7. f(x) = 3x² + 1

8. f(x) = x² 2

9. f(x) = x² + 2x

10. f(x) = 4x² + 1

11. f(x) = 2x² x + 1

12. f(x) = x² + 3x 2

13. f(x) = x³

14. f(x) = 1 x³

Example 5
