Use the parabola tool to graph the quadratic function. f(x)=2x^2−12x+19 graph the parabola by first plotting its vertex and then plotting a second point on the parabola.

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:
