a. Let C be the total number of Corona Virus cases in the United States by the end of
the t days since Feruary 14, 2020. (Let t = 0 represent Feb. 15, 2020.) Create a
scatter plot of the data. Take up the entire piece of graph paper. Make sure to label
the axes, and title your graph.
b. Does it look linear? Exponential, Quadratic?
c. Use the calculator to find the regression equation for this data. Express the equation
as a function, Cit) = a b.
Include screen shots of your data list entered, scatter plot on the calculator and the
regression equation screen
d. State a for both equations. What does it represent/mean in this context?
e. State b for both equations. What does it represent/mean in this context?
f. Estimate the total number of cases in the US by the end of the year, Dec. 31, 2020.
