Question

check my answer - A

The expression below shows the population of squirrels in a forest after 3x years:

f(x) = 30(1.03)3x

Which of the following is an equivalent function?

f(x) = 30(3.0900)x
f(x) = 30(1.0927)x
f(x) = 10(1.0927)x
f(x) = 10(3.0900)x

Answer 1

f(x)=30(1.03)3^x or f(x)=30(1.03)3^x or f(x)=30(1.03)3^x?

Answer 2

(a^n)m⟺a^n⋅^m f(x)=30(1.03)^3x⟹f(x)=30(1.03^3)^x⟹?

Answer 3

f(x)=30(1.03)^3x⟹f(x)=30(1.03^3)^x⟹f(x)=30(1.092727)^x

Answer 4

Ohh

Answer 5

and you can round that up to only say 1.0927

Answer 6

Your f(x) = 30(1.03)3x really should be written as\[f(x) = 30(1.03)^{3x}\]
via Equation Editor. If you're not comfortable with Equation Editor, please draw your equation so that you can show that 3x as the exponent it is.

Answer 7

Following boldjon's comment: You can write \[f(x) = 30(1.03)^{3x}\]

Answer 8

as\[f(x) = 30 *[(1.03)^{3} ]^x\]

Answer 9

i don't know how to use the equation thing well @mathmale

Answer 10

so the answer is B?

Answer 11

I just don't respond to "is it B?" questions. I'd be very happy to respond if y ou show your work and explain how and why you chose Option B.
