H
g(x) = _
A. g(x) = (x + 4)2 + 1
B. g(x) = (x - 4)2+1
c. g(x) = (x+422 - 1
D. g(x) = (x - 4)2 - 1

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
