The function f(x) = 4(3)x represents the growth of a dragonfly population every year in a remote swamp. erin wants to manipulate the formula to an equivalent form that calculates four times a year, not just once a year. which function is correct for erin's purpose, and what is the new growth rate?

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%.

i believe the answer is letter c) 8

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
