XAMPLES How does the graph ol the function below vary as c varies? souTON The graphs to t 1-t (the spedal as s r-2 and c--2, show to very diffrent looking curve. Befen drawing ary more graph let's see what members of dis famly have in common, Snce for any value of , they all have the raxis an a horteontal asymplabe A vertical asygtote weill occur whe equation we get x=-1± asymptote-1 because x. Solving this When c >1, thene is no vertical asymptote the top graph). Whee c-1 the graph has a single vertical This shows that F℃x).@-x" ncreases on the interval masimum point becomen lowers this in lained by the fact chst 1/ 1)-Oasn, A deceases from 1. the vertical asymptotes become
