Question

5. (1.5) Find the horizontal and vertical asymptotes for the following function. Sketch

its graph, including any intercepts.

y=-2x+4/3x-5

? ?

6. (1.5) Write an equation that defines a rational function with a vertical asymptote at

x = -5 and a horizontal asymptote at y =0

8. (2.1) Salmonella bacteria, found on almost all chicken and eggs, grow rapidly in a

nice warm place. If just a few hundred bacteria are left on the cutting board when a

chicken is cut up, and they get into a potato salad, the population begins

compounding. Suppose the number present in the potato salad after t hours is given

by f (t) = 500 ? 23t.

a. If the potato salad is left out on the table, how many bacteria are present 1

hour later?

b. How many were present initially?

c. How often do the bacteria double?

d. How quickly will the number of bacteria increase to 32,000?
