Question

What are the coordinates of the vertex of the function below? Write your answer in the form (x,y). y+9=-6(x+2)^2

Answer 1

this is parabola ,
the general form of a parabola of (a,b) vertex is
(y-b)=c(x-a)^2

Answer 2

so if u compare btw this formula and ur equation ,
a=-9
b=-2
c=-6
thus vertex is (-2,-9)
