Question

3. Ken has decided to raise rabbits but has been warned that the number of rabbits he will have will double every month. Ken started out with 30 rabbits and the function y = 30 • 2x models the number of rabbits he will have after x months. Which graph represents this function? (1 point)

Answer 1

For this case we have a function of the form:
 $y = A * (b) ^ x$
 Where,
 A: initial amount
 b: growth rate
 x: time in months.
 Therefore, in this problem the exponential function is: 
 $y = 30 * (2) ^ x$
 It is a growing exponential function.
