Vertex is #(-3,7)#

Explanation:

Comparing the above equation with the general equation of parabola # y = a*x^2+b*x+c # Here #a= -1 ; b = -6 ; c= -2 #
We know the Vertex(x-ordintae) # = -b/2*a or 6/2* -1 = -3#
#:. y = -(-3)^2 - 6*(-3) -2 = -9+18-2 = 7# So Vertex is #(-3,7)# [Ans] graph{-(x^2)-6x-2 [-20, 20, -10, 10]}
