To write a quadratic inequality that represents a graph, we typically need to know the form of the quadratic function and its relation to the x-axis (i.e., whether the graph is above or below the x-axis).
However, without a visual representation of the graph, it's difficult to determine the exact quadratic function or inequality. Generally, a quadratic inequality takes the form:
- \( ax^2 + bx + c < 0 \) (the graph is below the x-axis)
- \( ax^2 + bx + c > 0 \) (the graph is above the x-axis)
- \( ax^2 + bx + c \leq 0 \) (the graph is below the x-axis including the x-axis)
- \( ax^2 + bx + c \geq 0 \) (the graph is above the x-axis including the x-axis)
If you have information about the specific points, vertex, or behavior of the graph (such as whether it opens upwards or downwards), please provide that, and I can help formulate the appropriate quadratic inequality. Otherwise, here's a generic example of a typical form of a quadratic inequality:
Example: If the graph opens upwards and is above the x-axis: \[ y = x^2 - 4 \] Then the corresponding quadratic inequality could be: \[ x^2 - 4 > 0 \] This represents the regions above the x-axis for this specific quadratic function.
Please provide more details or describe the graph so I can assist you better!
