* = 169 In problems 12-13, the rational function R(x) = is given. a.) Factor and simplify to write R(x) in lowest terms. b) Find the horizontal asymptote or slant asymptote. c.) Find the vertical asymptote. d.) Determine the x-intercepts. e.) Determine the y-intercept. f.) Does the function contain a hole? If so, locate the coordinates of the point of discontinuity. g.) Determine where the graph is above the x-axis and where the graph is below the x-axis using the zeros of the numerator and denominator to divide the x-axis into intervals. h.) Sketch the function. 12. R(x) = (x-1)2 x2 - 1
