One of the common forms for quadratic functions is called vertex form, because it highlights the coordinates of the vertex of the function's graph.

Graph quadratic functions that are given in the vertex form a (x+b)²+c. For example, graph y=-2 (x-2)²+5.

The vertex is the lowest / highest point in the parabola, depending on whether the parabola opens up / down. The benefit of vertex form is that you can read the point directly from the equation.

The benefit of having the vertex is that you know the highest / lowest point in the graph and you know the graph will be symmetrical as it moves away from the vertex.

Now, there's many ways to find a vertex. Probably the easiest, there's a formula for it. And we talk about where that comes from in multiple videos, where the vertex of a parabola or the x …

Since the vertex is the point at which a parabola changes from increasing to decreasing or vice versa, it is also either the maximum or minimum y -value of the parabola.

3. Vertex All parabolas have a vertex, which is their tip. When a parabola is open up, its vertex will be the bottom-most point. When a parabola is open down, its vertex will be the top-most point.

We need to find the vertex and the axis of symmetry of this graph. The whole point of doing this problem is so that you understand what the vertex and axis of symmetry is.

You can still graph it by finding other points for the parabola. 1) Find the vertex point by converting the equation to vertex form, or by using the formulas to calculate the coordinates of the vertex: …
