#### Explanation:

A parabola has the form:

The vertex form of a parabola is:

To find the vertex

And to find the y coordinate we just evaluate in the original function with the value we just found:

The vertex is

If you want to have it in a nicer way:

graph{5(x+2/5)^2-19/5 [-10, 10, -5, 5]}

Click on the graph to see its vertex
