To determine the value of \( f(3) \) for a U-shaped graph, you would typically look at the specific graph in question. A U-shaped graph usually indicates a quadratic function with a minimum point, which could be modeled by a function of the form \( f(x) = ax^2 + bx + c \) where \( a > 0 \).
Since I can't see the graph, I can't provide the exact value of \( f(3) \) without further information on the function itself. If you can provide the equation of the function or specific points on the graph, I can help you calculate \( f(3) \). Otherwise, you would need to check the graph at \( x = 3 \) to determine the corresponding \( y \)-value.
