The parabola opens *downward,* and therefore its vertex is the maximum point. We see that the vertex is $(-1,5).$ Let's now find the axis of symmetry, which is the vertical line through the vertex that divides the parabola into congruent halves.

The equation of the axis of symmetry is $x=-1.$ Finally, we will find the $y-$intercept, knowing that it is the point where the graph intercepts the $y-$axis.

As we can see, the $y-$intercept is located at $(0,3).$
