The equation is
.
Because the
-term is squared, the equation represents a vertical parabola.
Find the focus of the parabola.
\Standard form of vertical parabola is
,
where
is vertex and focus
.

Rewrite the equation as
.
Compare the above equation with
.
and
.
Since
is positive, the parabola opens up.

The focus of
is
.
Therefore, the focus is
above the ground.
