The approximate number of accidents in one month,N, involving drivers between 16 and 30 years of age inclusive can be approximated by the equation or function N(a) = 2a squared - 80a + 500 where a = age of driver.
Calculate N(20) and explain what it means.
What's the domain of the function?
Can it be used to calculate the aprrox number of accidents for people 65 yrs of age?
I'm so lost. Please help me understand. Thanks
