\]
Linear
Exponential
Quadratic
None of these
Solution
Solution Steps
The given model \( F = C(1.08)^t \) is in the form of \( a \cdot b^t \), which is characteristic of an exponential model. The base of the exponent, 1.08, indicates growth.
Step 1: Identify the Model Type
The given equation is \( F = C(1.08)^t \). This equation is in the form \( a \cdot b^t \), where \( a = C \) and \( b = 1.08 \). This structure indicates that the model represents exponential growth.
Step 2: Confirm the Characteristics of the Model
In an exponential model, the variable \( t \) is in the exponent, which signifies that as \( t \) increases, \( F \) grows at a rate proportional to its current value. The base \( 1.08 \) indicates a growth factor of 8% per unit increase in \( t \).
Final Answer
The model type is exponential. Thus, the answer is \\(\boxed{\text{Exponential}}\\).
