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 1878
O a. P(x) - -3x? - 21x + 430; 136 people
b. P(x) - -7° + 21x + 480; 284 people
OC. P(x) = -3x? - 21x + 430; 70 people
O d. P(x) - -7° + 21x + 480, 200 people
