EXERCISES 23.1 In Exercises 17–20, for the function shown in the graph for the indi- cated exercise, find (a) S(2), and (6) lim f(x), if they exist. 17. Exercise 13 18. Exercise 14 19. Exercise 15 20. Exercise 16 In Exercises 1-4, make the given changes in the indicated examples of this section. Then solve the resulting problems. 1. In Example 2, change the denominator to x + 2 and then deter- mine the continuity. 2. In Example 8, change the numerator to 3r- 5x – 2 and find the resulting limit. Disregard references to Examples 6 and 7. 3. In Example 11, change the denominator to : + 2 and then find the limit ast-2. 4. In Example 14, change the numerator to 4r + 1 and find the re- sulting limit. In Exercises 21-24, graph the function and determine the values of x for which the functions are continuous.
