Graphing a quadratic equation in vertex form can be tricky. The vertex form looks like this:

y = a(x - h)² + k

In this equation, (h, k) is called the vertex.

Here’s how to graph it step-by-step:

1. Find the Vertex: First, you need to locate the point (h, k). This part can be a bit hard sometimes.

2. Decide the Direction: Next, you need to figure out if the graph opens up or down.

   • If a is greater than 0 (a > 0), it opens up.
   • If a is less than 0 (a < 0), it opens down.

3. Plot More Points: After finding the vertex, you can plot more points on the graph. This can be tricky without measuring carefully.

Tip: If you find it tough, you can change the equation to standard form:

y = ax² + bx + c.

Then, you can convert it to vertex form by using a method called completing the square. This can make things easier!
