Sect.1.5 Infinite Limits Limits at infinity Infinite limits
is undefined at x = 3 From the graph Consider the rational function And Table Left: Decreases without bound Right: Increases without bound
Now find the Limit graphically NOTE: the function increases or decreases without bound NOTE: not the same infinite limits do not exist
Limits Limits at infinity Infinite Limits
Identifying Infinite Limits Rational functions with undefined points in the denominator • Numerically: table of values • Graphically: examine end behavior • Analytically – compare behavior of numerator and denominator
Find Is the denominator approaching 0- or 0+ Examining the behavior of the denominator
Find Is the denominator approaching 0- or 0+
Infinite Properties • Let c and L be real numbers and let f and g be functions such that L > 0 L < 0
3) Find if and denominator
