As we can see from the graph, the parabola has a maximum, so it is opens downward.
The axis of symmetry is a vertical line which pass through the vertex. This line has an equation of x = -4.
The intercepts can be found as:
The x-intercepts are two: (-6,0) and (-2,0).
The y-intercept is (0,-3).
The coordinate of the vertex can be found at the point where the parabola changes direction. It is the maximum value for parabolas that open downwards.
In this case, the coordinates are (-4,1).
