Identify the initial amount a and the growth factor b in the exponential function.
A(x) = 30 ∙ 8.3x

8.3x, 30

30, 8.3x

8.3, 30

30, 8.3

1 answer

The exponential function is generally of the form \( A(x) = a \cdot b^x \), where \( a \) is the initial amount and \( b \) is the growth factor.

Given the function \( A(x) = 30 \cdot 8.3^x \):
- The initial amount \( a \) is the coefficient 30.
- The growth factor \( b \) is 8.3.

Therefore, the correct identification of the initial amount and the growth factor is:

30, 8.3
