Observe the graph:
The function is .
Identify the asymptotes, domain and range.
Identify the -values for is undefined.
is not defined for value of .
Thus, there is an asymptote at .
From , as a x values decrease, -values approach , and as -values increase, -values approach .
Thus there is an asymptote at .
The domain is all real numbers not equal to and the range is all real numbers not equal to .
The domain is all real numbers not equal to and the range is all real numbers not equal to .
