The functions f(x) = - 2.8x + 287 and Chances of 60-Year-Olds Surviving O g(x) =0.01x- - 4.9x + 375 model the chance, as a to Various Ages percent, that a 60-year-old will survive to age x. The 92 bar graph to the right shows the chances of 90- 60-year-olds surviving to various ages. Chance of survival 75- 64 60- a. Find and interpret f(80). 45- b. Find and interpret g(80). 30- c. Which function serves as a better model for the 15- 3.7 chance of surviving to age 80? 70 80 90 100 Age a. Select the correct choice below and fill in the answer box(es) to complete your choice. (Simplify your answers.) O A. f(80) = , which means that the chance of a 60-year-old surviving to the age of is 80%. O B. f(80) = , which means that the chance of a 60-year-old surviving to the age of 80 is % b. Select the correct choice below and fill in the answer box(es) to complete your choice. (Simplify your answers.) O A. g(80) = , which means that the chance of a 60-year-old surviving to the age of is 80%. O B. g(80) = , which means that the chance of a 60-year-old surviving to the age of 80 is%. c. Determine the better model for the chance of surviving to age 80. Choose the correct answer below. O A. The function g(x) is a better model. O B. The functions f(x) and g(x) are equally good models. O C. Neither f(x) nor g(x) are good models. O D. The function f(x) is a better model
