a. what variable should be represented by the axes?
what units should be displayed for the axes?
what scaling should be used for the axes?
b. find an equation of f. does your model fit the data well?
c. use the model f to estimate the number of boarding in 2001. the actual number was 622 million. what is the error in your estimate? ( the error is the different between the estimated value and the actual value)
d. the number of boarding in 2001 was low due to the terroist attacks on september 11,2001 by making…
I used a function to model data from 1990 through 2015. The independent variable in my model represented the number of years after 1990, so the function’s domain was {x| x = 0, 1, 2, 3, ......, 25}.Determine whether the statement makes sense or does not make sense, and explain your reasoning.
