\

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: \"\")

\

\"\"                            (Divide each side by \"\")

\

\"\"                                     (Cancel common terms)

\

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