Answer:
New growth rate = 32%
Step-by-step explanation:
∵ The exponential growth function is,
Where,
a = initial value,
b = growth rate per period,
x = number of period,
Here, the given function that shows the population growth every year,
By comparing,
Initial population, a = 4,
Let r be the rate per 4 times a year,
Thus, the function that shows the population growth four times a year,
According to the question,
Taking log both sides,
By graphing calculator,
Hence, the required function would be,
And, rate per period is 32%.
