Suppose that all the people in a country are ranked according to their incomes, starting at the bottom. Let x represent the fraction of the community making the lowest income (0x1);x-0.4 therefore, represents the lower 40% of all income producers. Let 1 x represent the proportion of the total income earned by the lowest x of all people. Thus, I 0.4 represents the fraction of total income earned by the lowest 40% of the population. The curve described by this function is known as a Lorenz curve. Suppose I(x) 0.92x2 + 0.08x. Complete parts a through e below.

Find and interpret (0.1) (Round to three decimal places as needed.)
