Answer:
The correct option is C). When it was purchased, the coin was worth $6
Step-by-step explanation:
Given function is f(t)=![6\times2^{t}](https://tex.z-dn.net/?f=6%5Ctimes2%5E%7Bt%7D)
Where t is number of years and f(t) is function showing the value of a rare coin.
A figure of f(t) shows that the graph has time t on the x-axis and f(t) on the y-axis.
Also y-intercept at (0,6)
hence, when time t was zero, the value of a rare coin is 6$
f(t)=![6\times2^{t}](https://tex.z-dn.net/?f=6%5Ctimes2%5E%7Bt%7D)
f(0)=![6\times2^{0}](https://tex.z-dn.net/?f=6%5Ctimes2%5E%7B0%7D)
<em>f(0)=6</em>
Thus,
The correct option is C). When it was purchased, the coin was worth $6
Parallel Lines: lines in a plane which do not meet. they do not intersect at any point, so your answer is B.
