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
