2.1.101 The f(x)--2.9x+286 and Chances of 9(x) 0.01x-5.1x+375 model the chanoe, as a percent, that a 60-year-old will survive to age x. The bar graph to the right shows the chances of Varñous Ages 90 84 76 surviving to various agos. 56 a. Find and interpret f(80). b. Find and c. Which g(80). serves as a better model for the 24 3.7 chance of surviving to age 807 0 80 90 100 Age OR. f(80)- which b. Select the correct choice below and fill in the answer box(es) to complete your choice. (Simplify your answers.) OA g 80,- , which means that the chance of a 60-year-old surviving to the age of @f is 80%. B. g(80)-31, 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. Neither f(x) nor g(x) are good models. O B. The function g(x) is a better model. ° C. The function f(x) is a better model. D. The functions f(x) and g(x) are equally good models. Click to select your answer and then click Check Answer. Clear All All parts showingExplanation / Answer
Option C is the answer.
The function f(x) is a better model since that represents more closely to the graph.
