Answer 1

The vertex is the lowest point on the graph.

The function is positive when x is less than the x-coordinate of the vertex.

The function is decreasing as x increases.

The domain of the function is all real numbers.

The range of the function is all real numbers less than or equal to the y-coordinate of the vertex.
