The functions is undefined at the point x=c. Let The function has a horizontal asymptote at In the previous example, So a=0 and c=1 here. So there is a horizontal asymptote at Which is just the x-axis. Why? As x gets very positive or negative, the ratio approaches the value a/c since b, d part becomes small. There is no asymptote if the numerator is just =0 #3 You guys do this one. 3.7 Page...
