Question

Identify the initial amount a and the growth factor b in the exponential function. f(x) = 620 • 7.8x

Answer 1

The given is f(x) = 620 · 7.8x

The standard equation for an exponential function is f(x) = Aoe^bx

where:
A is the initial amount
b is the growth factor which is constant
x is any real number

Therefore, the initial amount is 620 and the growth factor is 7.8

Answer 2

Answer:

Initial amount: 620

Growth Factor: 7.8

Step-by-step explanation:

Based on my research the Exponential Growth Formula is the following,

$f(x) = a * (1+r)^{t}$

In which:

1. f(x) is the total growth after a given time
2. a is the initial amount
3. r is the rate of growth in decimal form
4. t is the unit of time

Based on this information we can deduce that in the exponential function given to us in the question we can say that 620 is our initial amount and 7.8 is our growth factor.
