The image shows a graph of a quadratic function (a parabola) and a table where you are asked to determine whether specific expressions are positive, negative, or zero based on the graph. Let’s go through the key elements:

1. Graph: The parabola opens downward, meaning it represents a quadratic function with a negative leading coefficient. The vertex (highest point) seems to be on the y-axis, so the equation might have the form $y = -x^2$, or a similar downward-facing parabola.

2. Table: It contains the following expressions for classification:

   • $y$
   • $x$
   • $y - k$

To complete the table, we'll need to determine when each expression is positive, negative, or zero based on the graph of the quadratic function.
