Question

What is the the vertex of `y = -x^2-6x -2`?

Answer 1

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]}
