an exponential function has the equation y = (0.5)^x - 1. four points from a different function are shown in the table. for what values of x will the two functions be equal? A) x =0 B) x = -1, 0 C) x = 0, 1 D) the functions are never equal

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?
