Identify the initial amount a and the growth factor b in the exponential function.

a (x) = 30 x 8.3 ^x

680, 4.3x

4.3, 680

680, 4.3

4.3x, 680

Given the equation A (x) = 30 x 8.3 ^x, we can get the initial amount of A when x is equal to zero. Therefore:

A (0) = 30 * 8.3^0

A (0) = 30

In this case the equation grows by 8.3 times as x increases. Therefore the growth factor is 8.3.

Answers:

initial amount = 30

growth factor = 8.3

The answers are not in the given choices. I believe you are giving the wrong equation. If the correct equation here is:

A (x) = 680 x 4.3 ^x 

Then the answers are:

initial amount = 680

growth factor = 4.3

The answers are now in the choices given.

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

12/11c

or

12

c
