If the parabola is in vertex form (y=a(x-h)^2+k), the vertex is ((h,k))
If the parabola is in standard form (y=ax^2+bx+c), find the x-coordinate with (x=-frac{b}{2a})
Substitute that x-value into the equation to find the y-coordinate
The vertex is the point (left(-frac{b}{2a},, f!left(-frac{b}{2a}right)right))
If the parabola is (x=a(y-k)^2+h), the vertex is ((h,k))
Use the axis of symmetry to locate the vertex
For a graph, identify the highest or lowest point of the parabola
For a table of values, find the point where the parabola changes direction
