The functions $f(x)=-2.9 x+287$ and $g(x)=0.01 x^{2}-4.9 x+370$ model the chance, as a percent, that a 60 -year-old will survive to age $x$. The bar graph to the right shows the chances of 60 -year-olds surviving to various ages. a. Find and interpret $f(80)$. b. Find and interpret $g(80)$. c. Which function serves as a better model for the chance of surviving to age 80 ? Chances of 60-Year-Olds Surviving to Various Ages a. Select the correct choice below and fill in the answer box(es) to complete your choice. (Simplify your answers.)
