Step-by-step explanation:
we know that
The standard form of a vertical parabola is equal to
where
(h,k) is the vertex
the focus is (h, k + p)
and
the directrix is y = k - p
Part 1) we have
Convert to standard form
The vertex is the point
the directrix is equal to
----->
Part 2) we have
Convert to standard form
The vertex is the point
the directrix is equal to
----->
Part 3) we have
Convert to standard form
The vertex is the point
the directrix is equal to
----->
Part 4) we have
Convert to standard form
The vertex is the point
the directrix is equal to
----->
Part 5) we have
Convert to standard form
The vertex is the point
the directrix is equal to
----->
Part 6) we have
Convert to standard form
The vertex is the point
the directrix is equal to
