EXPLANATION;
Given that
The intial value of the ferrets is 6
The increase rate is 3
Follow the steps below
Recall, that the standard form of an exponential function is given below
[tex]\text{ y = ab}^x[/tex]
Where
a = initial value
b = ratio
[tex]\begin{gathered} \text{ y = 6 \lparen3\rparen}^x \\ \text{ let y = f\lparen x\rparen} \\ \text{ So,} \\ \text{ f\lparen x\rparen= 6 \lparen3\rparen}^x \end{gathered}[/tex]
Therefore, the correct answer is 6 (3)^x
