The graph shows a parabola opening downwards with its vertex at \( (0, 0) \). Based on the general form of a quadratic function for a parabola:

\[
y = ax^2 + bx + c
\]

Since the vertex is at \( (0, 0) \), the equation simplifies to:

\[
y = ax^2
\]

Now, we can estimate \( a \) by observing another point on the graph. From the image, it appears that the parabola passes through the point \( (2, -5) \). Using this point to find \( a \):

\[
-5 = a(2)^2
\]

\[
-5 = 4a
\]

Solving for \( a \):

\[
a = \frac{-5}{4}
\]

Thus, the equation of the parabola is:

\[
y = -\frac{5}{4}x^2
\]

Here are some related questions to explore:
1. What is the significance of the vertex in a parabola?
2. How would the graph change if \( a \) were positive?
3. How can we find the focus and directrix of the parabola?
4. What would be the effect of adding a linear term, \( bx \), to the equation?
5. How can you determine the axis of symmetry for this parabola?

**Tip:** The vertex form of a parabola is useful when identifying shifts or transformations, especially when the vertex isn't at the origin.

This example explores how to find the equation of a parabola with its vertex at the origin, passing through a specific point on the graph. The quadratic equation is derived using algebraic methods and graphing concepts. Suitable for students in Grades 9-12.
