Answer:
Option B is correct.
Initial amount (a) = 30 and growth factor(b) = 8.3
Step-by-step explanation:
An exponential function is of the form: [tex]y =ab^x[/tex] ....[1]
where
a represents the initial amount
b represents the growth factor and x is the variable
Given the function: [tex]A(x) = 30 \cdot (8.3)^x[/tex]
On comparing given equation with [1] we get;
a = 30 and b = 8.3
Therefore, the initial amount(a) = 30 and growth factor(b) = 8.3
