The table shows projections for the Year 2015 2040 2055
female population of a country (in Female Population
180
231 258
millions).
(a) Find a quadratic function f(x) = ax2 + bx + c that gives the female population in
millions) in year x, where x = 0 corresponds to the year 2000.
(b) Estimate the female population in the year 2050.
(a) The coefficient of x? in the equation is a =
(Do not round until the final answer. Then round to three decimal places as needed.)
The coefficient of x in the equation is b=
(Do not round until the final answer. Then round to one decimal place as needed.)
The constant in the equation is c= | 0
(Do not round until the final answer. Then round to one decimal place as needed.)
(b) The estimate for the female population in the year 2050 is million.
(Use the answer from part (a) to find this answer. Round to the nearest integer as
needed.)
