1. The question asks which graph to choose: first, middle, or last. 2. To answer this, we need more context about the graphs or the problem they represent. 3. If the graphs represent functions or data, consider what you want to analyze: intercepts, extrema, or overall shape. 4. Without specific details, it's best to start with the first graph to understand the baseline behavior. 5. Then, compare it with the middle and last graphs to see changes or trends. 6. This approach helps in learning and understanding differences step-by-step. 7. If you provide the graphs or their equations, I can help analyze them specifically.
