Question

( I will attach picture . ) *
A historian took a count of the number of people in a gold rush town for six years in the 1870s.

Find a quadratic function that models the data as a function of x, the number of years since 1870. Use the model to estimate the number of people in the town in 1887.

P (x) = –6x^2 + 25x + 475; 291 people
P(x) = –6x^2 + 25x + 475; 356 people
P(x) = –2x^2 – 25x + 425; 152 people
P(x) = –2x^2 – 25x + 425; 97 people
