Step 1 :Let's start by analyzing graph A (blue). If this is the function f, then graph B (red) should represent its first derivative, and graph C (green) should represent its second derivative. Let's check if this is true by looking at the slopes and concavity.
Step 2 :Since all checks passed, it seems that graph A represents the function f, graph B represents its first derivative, and graph C represents its second derivative.
Step 3 :\(\boxed{1. \: f A \: 2. \: f^{\prime} B \: 3. \: f^{\prime \prime} C}\)
