7r(3) = 3x+1 ac2 + x -2 119 solution 134 The denominator of this rational function is o when 156 ac + 2 - 2 = 0. 173 Solving this equation either by factoring or using the quadratic formula, we get x = -2 or x = 1. Because the 186 degree of the numerator is less than the degree of the 200 denominator, the value of this function is close to o when |x| is large. Thus the asymptotes of the graph of r are the lines x = -2, x = 1, and y = 0, as shown below: 203 20 203 213 222 234 The graph of -32+, on the interval [-6, 6], truncated 249 on the vertical axis to the interval [-20, 20]
