Answer:

The answer is the option A

When it was purchased (year
0), the coin was worth
\$3

Explanation:

we know that

The y-intercept of a function is the value of the function when the value of the independent variable is equal to zero

In this problem we have


f(t)=3(2^(t))

the independent variable is the variable t

so

Find the y-intercept

For
t=0 ------> year zero

Find the value of the function


f(0)=3(2^(0))=\$3

That means ----> When it was purchased (year
0), the coin was worth
\$3
