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.)
