Solve for y in terms of x; and complete the square to put into standard form. Read some answers from the finished equation. Intercepts follow, but solving for that on y-axis.

-----standard form

Parabola opens downward and vertex is a maximum.

Vertex: (1,8).
Symmetry Axis: x=1
y-intercept, by letting x be 0: (0,6).
x-intercepts, by let y be 0 and solve for x: (-1,0) and (3,0).
Domain: All Real Numbers
Range: Real Numbers less than or equal to 8.
