SAT Scores by Income The following bar graph shows U.S. critical reading SAT scores as a function of household income: 600 503 517 525 529 536 542 488 500 434 462 400 300 200 100 0. 0-20 40-60 80-100 120-140 160-200 Family income ($1,000) These data can be modeled by S(x) = 550 136(0.985)*, where S(x) is the average critical reading SAT score of stu- dents whose household income is x thousand dollars per year. Numerically estimate lim, S(x), and interpret the 59- answer. Critical reading SAT
