Using the regression feature on a graphing calculator, we input the given data and choose a quadratic regression model. This gives us the quadratic function y = -0.3144x² + 62.3744x + 111.9005. Rounding this to five decimal places, we get y = -0.31439x² + 62.37437x + 111.90054. The closest answer choice to this is B, with a slight rounding difference in the x-coefficient.
