15 POINTSWhat is the equation of the following graph in vertex form?(parabolic function going down from the left through the point negative four comma zero and turning at the point negative three comma negative one and going up through the point negative two comma zero and then through the point zero comma eight and continuing up towards infinity) y = (x − 3)2 − 1 y = (x + 3)2 − 1 y = (x − 4)2 − 2 y = (x − 4)2 + 8
