Question

The function models the number of accidents

Answer 1

f(60)=280

Explanation:

f(x)=0.4x²-36x+1,000

x=60→f(60)=0.4(60)²-36(60)+1,000

f(60)=0.4(3,600)-2,160+1,000

f(60)=1,440-2,160+1,000

f(60)=280

This mean that a driver of 60 years old will have 280 accidents per 50 million miles driven.
