Answer:
2,-1
Step-by-step explanation:
graph, find length between points (sqrt 20) and slope (-2). sqrt20/2=sqrt5.
change in y/change in x = -2, change in y squared + change in x squared= 5. solve system of equations to get x=1, y=-2, or x=-1, y=2. i think i did something wrong but the answer should be correct

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
