Provide an appropriate response.Find any horizontal or vertical asymptotes for the curve 
(Suggestion: Express the curve in parametric form 
and investigate what happens to x and y as ? varies.)
What will be an ideal response?
As ? ? 0+ or 2?-, x ? 0 and y ? 0. As ? ? 
-, x ? 4 and y ? +?. As ? ? 
+, x ? 4 and y ? -?. As ? ? 
-, x ? -4 and y ? -?. As ? ? 
+, x ?-4 and y ? +?. Thus the lines x = -4 and x = 4 are vertical asymptotes.
