We have a written in , and we want to rewrite it in .
In the given equation,
Let's now recall the vertex form of a quadratic function.
In this equation,
is the of the quadratic function, and the point
is the of the . By substituting our given values for
into the expression
we can find
So far, we know that the vertex lies at
To find the
we will substitute
in the given function.
coordinate pair of the vertex is
Moreover, since we already know that
we can rewrite the given function in vertex form.
