Provide an appropriate response.The bar graph shows the median, or middlemost, household income for African-Americans and Hispanics for three selected years in a certain state.
a) The formula I = 31,509 + 1789x - 106x2 models the median income of African-Americans, I, x years after 1990. Use the formula to find the median income for African-Americans in 2000.b) Does the value given by the mathematical model in part (a) underestimate or overestimate the actual median income for African-Americans shown by the bar graph. By how much?a) The formula I = 35,011 + 1859x - 112x2 models the median income of Hispanics, I, x years after 1990. Does the model
underestimate or overestimate the median income for Hispanics in 2016. By how much?
What will be an ideal response?
a) $38,799, b) overestimates by $22, c) underestimates by $25
