For a certain state, the function
f(x)=0.4x2−44x+1400
models the number of accidents, f(x), per 50 million miles driven as a function of a driver's age, x, in years, where x includes drivers from ages 16 to 74, inclusive. The graph of f is shown above. Use the equation for f to solve:
a) Find the number of accidents per 50 million miles driven for drivers age 25.
b) Find the number of accidents per 50 million miles driven for drivers age 55.
c) For what value of x does the graph have its lowest point? This is the age of drivers with the fewest accidents.
