A graphing calculator is required for some questions. Graph the function f(x) = x/(x² - 1). Use the graph to determine the following limits:

(a) The limit of f(x) as x approaches 1 from the right.
(b) The limit of f(x) as x approaches 1 from the left.
(c) The limit of f(x) as x approaches -1 from the right.
(d) The limit of f(x) as x approaches -1 from the left.
(e) The limit of f(x) as x approaches infinity.
(f) The limit of f(x) as x approaches -infinity.
