To find the vertex coordinates from the parabola, you can analyze the graph. The x (vertex) coordinate is just over the "x" axis, so the value is xvertex = 2.

The y (vertex) coordinate is y= 0 because it is the value that the parabola takes on that axis.

The axis of symmetry is the value in the "x" axis where the parabola is divided in half. So in this case is x = 2.

So the anser is x(vertex) = 2, y (vertex)=0 , and the axis of symmetry is x= 2.
