Answer:

The answer is the option A

When it was purchased (year [tex]0[/tex]), the coin was worth [tex]\$3[/tex]

Step-by-step 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

[tex]f(t)=3(2^{t})[/tex]

the independent variable is the variable t

so

Find the y-intercept

For [tex]t=0[/tex] ------> year zero

Find the value of the function

[tex]f(0)=3(2^{0})=\$3[/tex]

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