Applied Calculus (MAT 121)Dr. Day Thursday Feb 23, 2012 • Return to “the limit” • As the inputs approach some value, is there a recognizable pattern of approachment in the output values? • Vertical Asymptotes: Denominator Issues? • Horizontal Asymptotes: x∞, x−∞ MAT 121
Recall: Determining Limits • Calculate: How calculate limits? Try subbing in value! Simplify if possible and return to (a). Use a numerical approach: Sub in values closer and closer to the limiting input value. Look at a graph of the function and visualize the limit. Play the S & S Game: Identify SIZE and SIGN MAT 121
Vertical Asymptotes • Use Results: MAT 121
Horizontal Asymptotes • Use Results: MAT 121
Horizontal and Vertical Asymptotes Example: Determine all horizontal and vertical asymptotes for the function MAT 121
Putting It All Together: Curve Sketching Example: Sketch a graph of the function. Do not show graph on your calculator! MAT 121
