Question

need help!

Answer 1

Decide whether the function is an exponential growth or exponential decay function and find the constant percentage rate of growth or decay. (1 point)

f(x) = 2479 ⋅ 0.9948x

Exponential decay function; 0.0052%
Exponential growth function; -0.52%
Exponential growth function; 0.0052%
Exponential decay function; -0.52%

Answer 2

? is *

Answer 3

isn't that a linear function?

Answer 4

it is linear function @timo86m

Answer 5

let me ask a question

Answer 6

do you see a superscript in the question anywhere?

Answer 7

I said ? is * @camper4834

Answer 8

\[f(x) = 2479*0.9948^x\]

Answer 9

sorry about that strange symbol was added

Answer 10

yes @camper4834

Answer 11

okay its 0.9948^x which DOES make it an exponential function

Answer 12

if we have 1^x
then our graph is just a line that looks like this

Answer 13

if we have anything above 1
say 2 or 3 or 300 then our graph looks like this

Answer 14

if we have anything less than 1 our graph looks like this

Answer 15

okay but hoe can I find out if it's Exponential decay function or Exponential growth function? @camper4834

Answer 16

well lets take a look at this number
.9948

Answer 17

this is the number we want because it has the X attatched to it

Answer 18

since this number is SMALLER than one our function is DECAYING

Answer 19

okay! @camper4834

Answer 20

now by what percent is it decaying

Answer 21

answer b and d are ridiculous because your percent should NEVER be negative

Answer 22

yes @camper4834

Answer 23

to find this percent just take the number 1 and subtract our important number .9948

Answer 24

what is 1 - .9948?

Answer 25

once you have that you have your answer!

Answer 26

so it is Exponential decay function; 0.0052%!!!!! @chappy0729

Answer 27

correct

Answer 28

Thank you so much for explaining :) @camper4834
