\"\"

\

Observe the graph:

\

The veretex of the parabola is at \"\",So \"\" and \"\".

\

Since \"\" the graph, Let \"\" and \"\".

\

Vertex equation form is \"\".

\

Find \"\".

\

\"\"                    (Vertex form)

\

\"\"         (Substitute \"\" and \"\")

\

\"\"                             (Simplify)

\

\"\"                  (Subtract \"\" from each side)

\

\"\"                                   (Apply additive inverse property: \"\")

\

The equation of the parabola in vertex form is \"\".\"\"
