Which set of systems of equations represents the solution to the graph? upward opening parabola passing through negative 2 comma 3 to a minimum at negative 1 comma 2 and then increasing to 0 comma 3 and a downward opening parabola passing through negative 2 comma negative 1 to a maximum at 0 comma 3 and then decreasing through the point 2 comma negative 1 f(x) = –x2 + 2x + 3 g(x) = x2 + 3 f(x) = x2 + 2x – 3 g(x) = –x2 – 3 f(x) = x2 + 2x + 3 g(x) = –x2 + 3 f(x) = –x2 + 2x + 3 g(x) = x2 – 3
