3 Let L be a real number. 1. The statement means that for each ε>0 there exists an M>0 such that |f(x)-L| M. 2. The statement means that for each ε>0 there exists an N<0 such that |f(x)-L|<ε whenever x

4 The line y=L is a horizontal asymptote of the graph of f if or

5 If r is a positive rational number and c is any real number, then Furthermore, if x r is defined when x<0, then

6 Find the limit:

8 Find each limit. a. b. c.

9 1. If the degree of the numerator is less than the degree of the denominator, then the limit of the rational function is If the degree of the numerator is equal to the degree of the denominator, then the limit of the rational function is the ratio of the leading coefficients. 3. If the degree of the numerator is greater than the degree of the denominator, then the limit of the rational function does not exist.

10 Find each limit. a. b.

11 Find each limit. a.b.

12 Suppose that f(t) measures the level of oxygen in a pond, where f(t)=1 is the normal (unpolluted) level and the time t is measured in weeks. When t=0, organic waste is dumped into the pond, and as the waste material oxidizes, the level of oxygen in the pond is What percent of the normal level of oxygen exists in the pond after 1 week? After 2 weeks? After 10 weeks? What is the limit as t approaches infinity? (1,.5) (2,.6) (10,.9)

13 Let f be a function defined on the interval (a,∞) 1. The statement means that for each positive number M, there is a corresponding number N>0 such that f(x)>M whenever x>N. 2. The statement means that for each negative number M, there is a corresponding number N>0 such that f(x) N.
