<u>Given</u>:
The graph of shows the value of a rare coin in year t.
We need to determine the meaning of the y - intercept.
<u>Meaning of the y - intercept:</u>
Here, t represents the x - axis and f(t) represents the y - axis.
The value of y - intercept is the value of y when x = 0.
Hence, the the value of f(t) can be determined by substituting t = 0 in the function
Thus, we have;
Thus, the value of the y - intercept is 4.
The y - intercept represents the value of the rare coin in year 0.
Therefore, the meaning of the y - intercept is "When it was purchased (year 0), the coin was worth $4".
Hence, Option B is the correct answer.
