Answer:
Without a visual or additional information, it is difficult to determine the best function that models the stock data shown in the scatter plot.
However, we can make some observations based on the answer choices:
A. Y=0.3(2.94) +56.5 is not a linear function and does not seem to fit the general trend of the data.
B. Y=442x+53 is a linear function with a positive slope, but it does not seem to fit the general trend of the data.
C. Y=0.92)+58 is not a linear function and appears to be missing a variable.
D. Y=7.7x+47.7 is a linear function with a positive slope that seems to fit the general trend of the data.
Therefore, the best function that models the stock data shown in the scatter plot is likely D) Y=7.7x+47.7.
