To determine the standard form equation of a graph, you typically need to analyze the characteristics of the graph provided, such as the vertex, intercepts, and other notable points. However, since you didn't include a visual of the graph or any specific points from it, I can't directly identify which equation corresponds to the graph.
If you can describe the graph or its features (for example, its vertex, direction it opens, intercepts), I can help you choose the correct standard form equation from the provided options. Otherwise, if you have the graph in a specific context (parabola opening upwards or downwards, for example), I can help in providing tips to match the characteristics with the equations given.
