To determine the \( a \)-value of a quadratic function in standard form \( y = ax^2 + bx + c \), we need specific information from the graph of the quadratic. The \( a \)-value affects the width and direction (upward/downward) of the parabola.
If the graph opens upward, the \( a \)-value is positive; if it opens downward, the \( a \)-value is negative. The steepness or width of the parabola is influenced by the absolute value of \( a \) (larger values make it steeper, while smaller values make it wider).
Since you mentioned choices A: 3, B: 8, and C: -2, we can draw some conclusions:
- If the graph opens upwards, then either A (3) or B (8) could be the \( a \)-value.
- If the graph opens downwards, then C (-2) is the \( a \)-value.
Without the specific graph or additional information, I can't definitively say which option is correct. However, if you have the graph or more context, you can analyze it based on the criteria above.
If you provide the details of the graph, I can help identify the correct \( a \)-value more accurately!
