Q.12 If a quadratic has a vertex at (-2,2) and passes through (-1,0), what is its equation in standard form?

y = (x + 2) 2 + 2

y = - (x + 2) 2 - 2

y = -2 (x + 2) 2 + 2

y = -2 (x-2) 2 + 2

Si una cuadrática tiene un vértice en (-2,2) y pasa por (-1,0), ¿cuál es su ecuación en forma estándar?
y = (x + 2)² +2
y = -(x + 2)²-2
y=-2 (x + 2)2 +2
y=-2 (x-2) 2+2
