Which is the equation of the parabola? Coordinate plane with a parabola facing down with vertex at 2 comma negative 3, the point 2 comma negative 5 and a horizontal line going through 0 comma negative 1 y = −one eighth(x + 3)2 + 2 y = one eighth(x − 3)2 − 2 y = one eighth(x + 2)2 + 3 y = −one eighth(x − 2)2 − 3
