Put your function into standard, namely , form.

The -coordinate of the vertex is given by

The -coordinate of the vertex is the value of the function at the -coordinate of the vertex, to wit:



The line of symmetry is the equation

The maximum or minimum value of the function is . It is a minimum if the lead coefficient (the in ) is positive and a maximum if it is negative.
