To determine which statement is true based on the graph of the quadratic parabola, we need to analyze the features of the parabola.
1. **c-value of the equation in standard form**: The c-value (the y-intercept) is found where the parabola intersects the y-axis. If the graph shows the y-intercept at -10, then the c-value is indeed -10. If it is not, then that statement is false.
2. **Vertex**: The vertex of the parabola can be identified as the highest or lowest point (depending on whether it opens upward or downward). If the vertex is at (3, -10), that would need to correspond with the actual graph.
3. **c-value of -1**: Similar to the first point, this depends on where the parabola intersects the y-axis.
4. **a-value is negative**: If the parabola opens downward, then the a-value is negative. If it opens upward, the a-value is positive.
To select the correct response, compare these points with the actual graph you see. If the parabola opens downward, the statement about the a-value being negative is true. If the vertex is indeed at (3, -10), that statement is true as well.
Assuming typical characteristics of parabolas, if you find the parabola opens downward, the most likely correct answer is **"The a-value is negative."**
If you have access to the graph and can determine the specifics, please verify against these criteria.
