Question

Write an equation y = a(b)^x to model the given data. Let x = number of days after March 11, and let y = the total number of positive Covid-19 cases in NYC.

March 11 = 53 total cases

March 12 = 88 total cases

March 13 = 137 total cases

March 14 = 185 total cases

Answer 1

I entered these data values into the TI=84, did an exponential regression on it and got the following:

y=36.55(1.52)^x
