Axis of symmetry: x=0h. direction- down

Answer 1

Answer:

g. Axis of symmetry: x = 0

h. direction- down

Explanation:

The parabola we are given is

$y=-3x^2-9$

The negative sign in from of x^2 tells us that the parabola opens downward.

Therefore, choice h is a correct answer.

Furthermore, since the parabola is neither shifted to the left nor right (because a = 0 in (x + a)^2 ), it is symmetric with respect to the x-axis. In other words, the axis of symmetry for the parabola is x = 0.

Therefore, choice g is a correct answer.

Our answers can be confirmed by looking at the graph of the parabola.
