Let (x) = (x 2 - 1) / (|x| - 1). a. Make tables of the values

Question:

Let ƒ(x) = (x2 - 1) / (|x| - 1).

a. Make tables of the values of ƒ at values of x that approach c = -1 from above and below. Then estimate limx→ -1 ƒ(x).

b. Support your conclusion in part (a) by graphing ƒ near c = -1 and using Zoom and Trace to estimate y-values on the graph as x→ -1.

c. Find limx→ -1 ƒ(x) algebraically.
