Unformatted text preview: yintercept (if any) by evaluating f (0). Plot that point. e) Find and plot one or two points prior to and beyond each of the vertical asymptotes. e) Graph the function Check your answer graphically using a graphing utility, and numerically, by creating a table of values. 1. 16 12 ) ( 2 2 − − = x x x f a ) domain = {x:x ≠4, 4} b) The zeros are at 12 12 , − c) The vertical asymptotes are at x = 4 and x = 4 and the horizontal asymptote is y = 1. d) The yintercept is ¾ . The graph : 2. 9 ) ( 2 2 − = x x x f a) Domain = {x: x ≠3, 3} b) There is one zero at x = 0. However, it is a double zero so the graph will be tangent to the xaxis at that point. c) There are two vertical asymptotes, at x = 3 and x = 3. The horizontal asymptote is y = 1. d) The yintercept is 0....
