Identify the initial value in each formula below, and state whether the formula models exponential growth or

kaheart [24]

Answer:

Intial Value: f(t) = 2 , Exponential Growth

Step-by-step explanation:

To find the initial value, all we have to do is find the value of f(t) at t = 0

In this case the given equation becomes

$f(t) = 2(\frac{5}{3})^0$

from the law of indices we know that any number with the power 0 is equal to 1 (except 0 with the power 0)

$a^0 = 1$

hence the above equation becomes

$f(t) = 2(1)\\ f(t) = 2$

so the initial value is 2.

To find out whether this is exponential growth or exponential decay we need to see whether the base value of the power t is less than 1 or greater than 1, i.e. from

$(\frac{5}{3} )^t$

$\frac{5}{3}$ > 1 or $\frac{5}{3}$ < 1

if the value is greater, then with each increment in power, the total value will increase while if it is less than 1 then with each increment in power the total value will decrease.

Hence since $\frac{5}{3}$ > 1 then this is an exponential growth
