According to data, the accident rate as a function of the age of the driver in years x can be approximated by the function f(x)= 79.7-2.83x+0.0252x for 16<x<85 Find the age at which the accident rate is a minimum and the minimum rate. ..... How is the age determined for the age at which the accident rate is a minimum? O A. Substitute 16 for x and solve for f(x) because the minimum value of the function always occurs at the minimum value of x in the interval. O B. Determine the x-value of the vertex O C. Determine the y-value of the vertex O D. Substitute 0 for x and solve for f(x). The age at which the accident rate is a minimum is (Round down to the nearest whole number.) The minimum rate is about %. (Type an integer or decimal rounded to the nearest tenth as needed.)
