Question

What is the axis of symmetry of the graph of y = –(x + 3)2 – 6?

Answer 1

Would you like the formula?

Answer 2

so (3,-6)?

Answer 3

the parabola\[y-k=a(x-h)^2\]has vertex at\[(h,k)\]find the vertex, then decides if the graph opens up-down or sideways.
Depending on that the axis of symmetry will either have equation
x=h
or
y=k

Answer 4
