Answer:
B. Exponential Function; base = 2; initial value = - 3.8
Step-by-step explanation:
hey there,
< The formula for exponential functions is [tex]A_{t} = A_{o} e^{kt}[/tex]. The function given DOES follow this formula (At = y, -3.8 = Ao, e = 2, k = 1, t = x) so that means it is an exponential function. C cannot be the answer.
You already know that e is the base in called the "natural base". e is equal to a number around 2. In this function, they just put it as "2". So we know that the base is equal to 2.
Ao means initial value and At means value after the experiment is done. Here, we can see Ao = -3.8 so that is the initial value.
base = 2; initial value = - 3.8 >
Hope this helped! Feel free to ask anything else.
