find and label the vertex and the line of symmetry. graph the function.
f(x)=-2(x+3)^2
F(x) = Y = -2(X + 3)^2 This is a Y Parabola. Vertex form: Y = a(X-h) + K.
Y = -2(X + 3)^2 + 0, coordinates of
vertex: V(X,K), V(-3,0), The line of
symmetry (axis of symmetry):X = -3 =
a vertical. To graph the Eq., select
values of X to the left and right of
vertex and calculate the corresponding
values of Y: (-5,-8) , (-4,-2) ,
V(-3,0) ,(-2,-2) ,(-1,-8).
