In the year 2000, in an African game park it was estimated that there were approximately 700 wildebeest and that
their population was increasing at 3% per year. At the same time, in the park there were approximately 1850 zebras
and their population was decreasing at the rate of 4% per year. Use a calculator to plot the graphs of both functions.
a. After how many years was the number of wildebeest greater than the number of zebras?
b. It is also estimated that there were 1000 antelope and their numbers were increasing by 50 per year. After how
many years was the number of antelope greater than the number of zebras?
