To determine the vertex form of the equation of a parabola, we can use the general vertex form, which is given by:

\[ y = a(x - h)^2 + k \]

In this equation, \((h, k)\) is the vertex of the parabola.

Since I cannot see the image you referenced, I will guide you on how to find the vertex form of the parabola based on the graph. Here are the steps to determine the vertex:

  1. Identify the Vertex: Look at the graph to find the vertex of the parabola. It will be the point where the parabola changes direction (i.e., the minimum point for an upward-opening parabola).

  2. Read Coordinates: Once you've identified the vertex, note down the \(x\) and \(y\) coordinates of that point. Let's say the vertex is at the point \((h, k)\).

  3. Determine the Value of \(a\):

    • Choose another point on the parabola from the graph (not the vertex) to determine the value of \(a\).
    • Use the coordinates \((x_1, y_1)\) of that point in the equation to solve for \(a\): \[ y_1 = a(x_1 - h)^2 + k \]
  4. Construct the Equation: After determining \(a\), substitute \(h\), \(k\), and \(a\) back into the vertex form equation.

Please go ahead and identify the vertex and a point on the parabola using the instructions above, and then you can fill in the values into the vertex form of the equation.
