Question

I really need some help :(

Answer 1

The question?

Answer 2

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?

Answer 3

Do you think you can help me out? @juliastevens

Answer 4

As much as i would love two, im not good at that kind of math, im very sorry.

Answer 5

Ok :/

Answer 6

do you know anyone who could?

Answer 7

@mathway

Answer 8

@mathmate

Answer 9

Do you know which number in the formula represents the growth rate?

Answer 10

@angiepangie0726

Answer 11

3? i think

Answer 12

right, so if it's 3 for the whole year, divide it by 4 to get the growth rate every quarter

Answer 13

ok, 0.75

Answer 14

these are my choices

f(x) = 4(3)x; growth rate 300%
f(x) = 4(3)x, growth rate 4%
f(x) = 4(1.32)x; growth rate 4%
f(x) = 4(1.32)4x; growth rate 32%

Answer 15

would it be b?

Answer 16

@angiepangie0726
Is the formula an exponential? If it is you need to put the ^ sign to show that it is an exponential function.
f(x)=4(3^x) is the same as \(f(x)=4(3^x)\)

Answer 17

4(3)^x

Answer 18

nvm. I think the growth rate is 2 on the year. I think the formula's something like
a(1 +r)^x

Answer 19

I'm not at all sure about this anymore. talked myself in circles :/
