For a certain population the growth rate G, measured in thousands per year, depends on the population n, measured in thousands.  The relationship is

.

?

A:  Make a graph of G versus t. Include populations of up to 120,000 (corresponding to ).B:   Explain what is happening to the population at  thousand and at  thousand.C:  Over what population ranges is G negative?D:  Explain in practical terms what is happening to the population over the population ranges you found in part C.



What will be an ideal response?


A:  

?

?

B: The growth rate is zero, so the population is not changing.  

?

C: From 0 to 22 thousand and above 98 thousand

?
