To find the vertex of our parabola, we are going to use the vertex formula: For a quadratic of the form it vertex is given by , . We can infet from our parabola that and . So lets replace those values in our formula: The vertex of our parabola is
Now to find our second point, we are going to evaluate our parabola at Our second point is
We can conclude that we can graph the parabola using its vertex and the point as follows:
