For each function, identify the points of discontinuity, holes, intercepts, horizontal asymptote, vertical asymptote(s) and domain. Then sketch the graph.
Answer Key for #3
Discontinutities at x=3 and x=-3
Holes: None
Horizontal Asymptote: y=1
Vertical Asymptotes: x=3 and x=-3
X-Intercepts: (2,0) and (-2,0)
Y-Intercept: (0, 4/9)
Domain: All reals except -3 and 3
Consider the rational functions on the right.
Use the items on the left to identify each function's:
◆ Domain
◆ Points of discontinuity (and the type of discontinuity each represents: removable or non-removable)
