Let h(x) = (x2 - 2x – 3)/(x2 - 4x + 3). a. Make a table of the values of h at x = 2.9,...

Let h(x) = (x² - 2x – 3)/(x² - 4x + 3).

a. Make a table of the values of h at x = 2.9, 2.99, 2.999, and so on. Then estimate What estimate do you arrive at if you evaluate h at x = 3.1, 3.01, 3.001, … instead?

b. Support your conclusions in part (a) by graphing h near c = 3 and using Zoom and Trace to estimate y-values on the graph as

c. Find algebraically.
