find the vertex of the parabola represented by each equation.
1)
The vertex of the parabola whose equation is
is
(
,
)
where
= the discriminant
For
,
,
,
So vertex = (
,
) = (
,
) = (
,
) = (
,
)
2)
You mistyped that one because it should not have two equal signs. But it's
done the same way.
If the second equal sign was supposed to have been a +, then
vertex = (
,
)
If the second equal sign was supposed to have been a -, then
vertex = (
,
)
