Respuesta :

Answer:

C. The initial amount in the account was $2,500.

Explanation:

The function that represents the amount, in dollars, in a savings account after x years is given as:

[tex]f\mleft(x\mright)=2,500\mleft(1.012\mright)^x[/tex]

When x=0 (Initially)

[tex]\begin{gathered} f\mleft(0\mright)=2,500\mleft(1.012\mright)^0 \\ =2,500\times1 \\ =\$2,500 \end{gathered}[/tex]

Therefore, the initial amount in the account was $2,500.
