Consider the function f(x) = x^2–4 / x-2 (a) Fill in the following table of values for f(x):
X= 1.9 1.99 1.999 1.9999 2.0001 2.001 2.01 2.1 f(x) = = 3.9 3.99 3.999 3.9999 4.0001 4.001 4.01 4.1 (b) Based on your table of values, what would you expect the limit of f(x) as x approaches 2 to be?
lim_x--> 2 x^2/4 / x-2 = ___
(c) Graph the function to see if it is consistent with your answers to parts (a) and (b). By graphing, find an interval for x near 2 such that the difference between your conjectured limit and the value of the function is less than 0.01. In other words, find a window of height 0.02 such that the graph exits the sides of the window and not the top or bottom. What is the window? ____ <= x <= ____
____ <= y <=____
