A parabola opens toward to the location of focus with respect to the vertex.
When the vertex and focus has same y-values, it implies that the parabola opens sideways (left or right).
When the vertex and focus has same x-values, it implies that the parabola may opens upward or downward.
The given focus of the parabola is located above the vertex
. Both points has the same value...
A parabola opens toward to the location of focus with respect to the vertex.
When the vertex and focus has same y-values, it implies that the parabola opens sideways (left or right).
When the vertex and focus has same x-values, it implies that the parabola may opens upward or downward.
The given focus of the parabola is located above the vertex
. Both points has the same value of
.
Thus, the parabola opens upward. In this case, we follow the standard formula: . We consider the following properties:
vertex as
focus as
directrix as
Note: is the distance of between focus and vertex or distance between directrix and vertex.
From the given vertex point , we determine h =0 and k=0.
From the given focus , we determine
and
.
Plug-in on
. we get:
Plug-in the values: ,
, and
on the standard formula, we get:
as the standard form of the equation of the parabola with vertex
and focus
.
