Question
Which of the following could be an equation for the graph shown in the x y-plane above?
The correct answer is:
intercepts of line are (0,4) and (12,0)
The line equation is
12(y - 4) = -4(x - 0)
3(y-4) = -(x-0)
3y – 12 = -x
3y = -x + 12

There were no jackrabbits in Australia before 1788 when 24 jackrabbits were introduced. By 1920 the population of jackrabbits had reached 10 billion. If the population had grown exponentially, this would correspond to a 16.2% increase, on average, in the population each year. Which of the following functions best models the population p(t) of jackrabbits t years after 1788?
