Solve the problem.The table shows the number of deaths due to car accidents in a certain city in various years. 
Let 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 to find the vertex and use the data for the year 2017 to find the value of a.
A. f(t) = -1.24(t - 3)2 + 219
B. f(t) = -7.75(t - 3)2 + 270
C. f(t) = -1.24(t - 3)2 + 270
D. f(t) = -7.75(t - 3)2 + 219
