Unformatted text preview: General Model for Exponential Growth or Decay N ( t ) = N e kt where N = the value of N at time zero k = growth or decay constant t = time Solve. The rabbit population in a forest grows at the rate of 8% monthly. If there are 250 rabbits in July, find how many rabbits (rounded to the nearest whole number) should be expected by next July. ( Hint: Use the exponential growth function N ( t ) = N e kt .) Solve. a.) Find the exponential growth function for a city whose population was 34,600 in 2001 and 39,800 in 2004. Use t = 0 to represent the year 2001. b.) Use the growth function to predict the population of the city in 2008. Round to the nearest thousand .
