What is the quadratic function that best models this population as a function of the number of years after 1970? Let x represent the number of years after 1970 and y represent the number of millions of people in this labor pool. y= (-0.225 )x + ( 22.295)x + ( 360.420") (Type integers or decimals rounded to three decimal places as needed.) b. Use technology with the model to find the maximum size of this population before it begins to shrink. The maximum size of the labor pool population is approximately 912 million. (Round to the nearest whole number as needed.) It will occur in the year 2020
