Solve the problem.The table shows the number of deaths due to car accidents in a certain city in various years. 
Let n = f(t) be the number of deaths due to car accidents at t years since 2012. Find a quadratic equation for f in vertex form. Use the data for the year 2015 as the vertex and use the data for the year 2017 to find the value of a.
A. f(t) = -4.25(t - 3)2 + 202 B. f(t) = -12.75(t - 3)2 + 270 C. f(t) = -2.04(t - 3)2 + 270 D. f(t) = 4.25(t - 3)2 + 202
