How do you find the ordered pair of the vertex of the parabola y=-3x^2-6x+4

y=-3x^2-6x+4

Letting b = -6  and a = -3.....the x coordinate of the vertex is given by

-b/[2a]  =  -(-6)/ [2(-3)]  = 6/-6  = -1

And to find y, put this value back into the function

y = -3(-1)^2 -6(-1) + 4  =  -3 + 6 + 4  = 7
