1. The problem is to analyze the function given by the data and extract meaningful information. 2. Since the data is not a clear mathematical expression, we focus on the metadata and the function name "SEFTGraph plz" which suggests a graph of a function. 3. The function is not explicitly given, so we cannot write an explicit formula. 4. However, the "desmos" field can be used to plot a function if provided. 5. Without a specific function, we cannot determine intercepts or extrema. 6. Therefore, we provide an empty minimal desmos field and indicate one question answered (the analysis of the data). Final answer: The data does not contain a clear function to analyze mathematically.
