Let (x) = (x 2 - 9)/(x + 3). a. Make a table of the values of

Let ƒ(x) = (x² - 9)/(x + 3).

a. Make a table of the values of ƒ at the points x = -3.1, -3.01, -3.001, and so on as far as your calculator can go. Then estimate lim_x→-3 ƒ(x). What estimate do you arrive at if you evaluate ƒ at x = -2.9, -2.99, -2.999,cinstead?

b. Find lim_x→-3 ƒ(x) algebraically, as in Example 7.
