In order to find the vertex, we first need to find the x-coordinate of the vertex.
To find the x-coordinate of the vertex, use this formula: .
Start with the given formula.
From , we can see that , , and .
Plug in and .
Negate to get .
Multiply 2 and to get .
Divide.
So the x-coordinate of the vertex is . Note: this means that the axis of symmetry is also .
Now that we know the x-coordinate of the vertex, we can use it to find the y-coordinate of the vertex.
Start with the given equation.
Plug in .
Square to get .
Multiply and to get .
Combine like terms.
So the y-coordinate of the vertex is .
So the vertex is
.
