Answer:
a) 2*4^n b)2048 c) n > 9.46578
Step-by-step explanation:
The initial population was the two parents ( male and female)
After first year, the population quadruples = 2*4 = 8
After second year, the population = 2*4*4= 32
After third year, the population = 2" 4*4*4
After n number of years, the population = 2*4^n
b) after 5years, the population = 2*4^5 =2048
C) for the population to exceed 1million the equation becomes 2*4^n > 1 000 000
4^n > 500000, take log of both side
nlog4 > log 500000
n > log 500000/log(4) > 9.46578
