Answer:
Initial population size=200
The function represents a growth
Step-by-step explanation:
Equation to calculate population size after time, t
P(t) = 200(1.18)^t
To find initial population size we will take t = 0
P(0) = 200(1.18)^0
= 200(1)
= 200
To find that function represent growth or decay
P(1) = 200(1.18)^1
= 200(1.18)
= 236
Its means that after a year population increases. Hence, function represent growth.
By what percentage does the population change each year?
(236 - 200 / 200) * 100%
= 235%
