N 44 Using U.S. Census Bureau projections from 2020 to 2060, the number of U.S. females under the age of 18, in millions, can be modeled by the function N = 0.150x + 37.4 where x is the number of years after 2020. N (a) Use a graphing calculator to graph this equation for the range x-min 0, x-max =40; N-min = 35, N-max = 45. N 44 42 40 38 36 30 A 44 42 12 40 10 10 20 20 40 38 36 10 10 30 83 20 20 44 40 42 40 38 30 30 36 10 10 20 20 42 40 39 38 36 30 40 10 20 30 (b) The point (30, 41.9) lies on the graph of this equation. Explain its meaning. The model projects that the number of U.S. females under the age of 18 will be 41.9 million in 2030. The model projects that the number of U.S. females under the age of 18 will be 30 million in 2939
