Based on the graph you provided, it appears to be a parabola opening upwards, indicative of a quadratic function. The vertex form of a quadratic function is most suitable to describe the graph given the clear vertex shown in the plot. The vertex of the parabola seems to be at the point \( (0, -4) \), and it is symmetric about the y-axis.

The general vertex form of a quadratic equation is:
\[
y = a(x - h)^2 + k
\]
where \( (h, k) \) is the vertex of the parabola.

Here, \( h = 0 \) and \( k = -4 \). To find the coefficient \( a \), we can use another point on the graph. Looking at the graph, it looks like the point \( (2, 0) \) also lies on the parabola. Plugging in this point into the equation:
\[
0 = a(2 - 0)^2 - 4
\]
\[
0 = 4a - 4
\]
\[
4a = 4
\]
\[
a = 1
\]

Thus, the equation of the parabola is:
\[
y = (x - 0)^2 - 4
\]
or simply
\[
y = x^2 - 4
\]

This function should correctly describe the graph you provided. Would you like any further explanation on this? Here are some questions you might consider:

1. How would the graph change if the coefficient \( a \) were greater than 1?
2. What would the graph look like if \( a \) were negative?
3. How does shifting \( h \) and \( k \) in the vertex form affect the graph?
4. Can you describe how to find the intercepts of this quadratic graph?
5. What are the applications of quadratic functions in real-world scenarios?

**Tip**: Remember, the vertex form is very useful for quickly identifying the maximum or minimum point of a parabola and its line of symmetry.

Write a function in any form that would match the graph shown below.

This problem involves identifying the quadratic function that corresponds to the graph of a parabola. The vertex of the graph is at (0, -4), and another point on the graph is (2, 0). Using these key points, the vertex form of the quadratic equation is derived step by step, explaining concepts like vertex form, symmetry, and how to find the coefficient a.
