# How do I find the vertex, axis of symmetry, y-intercept, x-intercept, domain and range of #y = -x^2 + 6x -9#?

##### 1 Answer

This one is easy to factor to find the vertex to be the point

#### Explanation:

You can factor

This means the parabola opens downward with a vertex (high point in this case) at

For the

The domain is the entire real number system

The graph is shown below. Make sure you think about all these answers in relation to the graph.
