Red bird's flight path can be modeled by the quadratic equation y=-x^2+12x-11. what is the vertex? what is the axis of symmetry? what was the total distance? what is the domain and range?

Quadratic Equation: 

What is the Vertex?
Vertex Form: , where (h, k) is the vertex of the parabola. 






Vertex is (6,25)

Axis of Symmetry?
This is just the h value so the AoS = 6

Total Distance? (I assume x-intercepts)



x-intercepts are (1,0) and (11,0) so in between them was the flight.

Domain and Range?
I'm not sure what domain and range are but I found a calc online for it and it says
Domain: (−∞,∞),{x|x∈R}Range: (−∞,25],{y|y≤25}

What is the question
