Vertex
Re arrange the equation as follows
y=
=
=
=
The vertex is
Minimum value is y=7/4 and maximum is
In the general case, the coordinates of the vertex for a function of the 2nd degree
(where
In our particular case, the vertex will have the following coordinates:
The vertex is the point
We can see that the function has a minimum, that is
The axis of symmetry is a parallel line to the
