The population of a certain country was approximately 75 million in 1900, 175 million in 1950, and 375 million in 2000. Construct a model for this data by finding a quadratic equation whose graph passes through the points (0,75), (50,175), and (100,375). Use this model toestimate the population in 2050.Let x be the number of years since 1900 and y be the population in millions.y=(Use integers or decimals for any numbers in the expression.)According to the model, what will the population be in the year 2050?milliony =CActivate Windows
