Answer:
Second and last
Explanation:
The vertex form of a quadratic function is written as: a(x-h)^2+k where (h,k) are the coordinates of the vertex
The equation y =-(x-0.5)^2+9
Then the vertex of this graph is (0.5,9)

The equation -(x-0.5)+9 has a negative leading factor so the parabola will open down then it will have a maximum
