Consider the function f(x)= x+1 / x-1
(a) Find the domain of f(a) (b) Give the horizontal and vertical asymptotes of f(x), if any Enter the equations for the asymptotes. If there is no horizontal or vertical asymptote, enter NA in the associated response area. c) Give the intervals of increase and decrease of f(x) Note: Use the letter U for union. To enter oo, type infinity If the function is never increasing or decreasing, enter NA in the associated response area increasing?
(d) Give the local maximum and minimum values of f(x). Enter your answers in increasing order of the x-value. If there are less than two local extrema, enter NA in the remaining response areas and the corresponding drop-down menu Include a multiplication sign between symbols. For example, a • π
(e) Give the intervals of concavity of f(x). (f) Give the inflection points of f(a) Enter your answers in increasing order of the ar-coordinate. If there are less than two points of inflection, enter NA in the remaining response areas Include a multiplication sign between symbots.
