It should be answer B. With 0.0321 there is a zero both before and after the decimal, while answer A only has one before the decimal.
The function represents the number of accidents (f(x)) per 50 million miles driven as a function of the driver's age (x).

f(45) indicates that you have to find the value of f(x) when x=45, to do so replace the equation of the function with the value of x and solve for f(x)

For x=45 years f(x)=190
f(45)=190; This value indicates that 45-year-old drivers had 190 accidents per 50 million miles driven.
