Solution :

The model is :

Year                     1870      1871      1872     1873      1874     1875        1876

Population            365       384       393      392       381       360        329

It is given that a historian counted the number of people in the Gold Rush town for a 6 years staring from 1870.

Therefore the quadratic function which models a data as a function of the number of years from 1870 i.e. x is given by

[tex]$P(x) = -5x^2+24x+365$[/tex]

And the number of people present the town of Gold Rush in the year 1878 can be found by using the model is 237.
