Brianna is working on her homework and is asked to state the domain and range for *y* = tan*θ*. She enters the equation on her graphing calculator and sets her Xmin to

Explain to Brianna the domain of

and how to use the graph to make sense of it.Where are the asymptotes located? What does this mean about the domain?

The second part of Brianna's problem asked her to graph the transformed equation

. As she entered the equation into her graphing calculator, the screen went blank. (Her batteries were dead.) Explain to Brianna how she can use her first graph to sketch her transformed graph . Include a labeled sketch. Does this transformation have a different domain from that in part (a)? If so, how is it different? What is the range for each function

*y*= tan*θ*and? Justify your answers completely. How does the transformation affect the positions of the asymptotes?
