The vertex is at

The axis of symmetry

Step-by-step explanation:

Note: You can answer all the questions looking at the graph

We have the function (I am assuming this) such that

We note that

once we have a difference of squares

Therefore, we have a quadratic function.

So

The vertex is

Therefore, the vertex is at

As we know the vertex, we conclude that the axis of symmetry

The x-intercepts occur at

So, the left x-intercept is and the right x-intercept is

As I stated in the beginning, the domain is the set of all real numbers. Precisely,

Once, we know the vertex, we also conclude that the Range is

Greater than or equal to -9

answer: h
