Answer:

  A

Step-by-step explanation:

It is usually useful to consider the inequalities by looking at variable terms with positive coefficients in relation to the inequality symbol. If the inequality symbol includes the "or equal to" case (≤ or ≥), then the boundary line is solid. Otherwise, it is dashed.

  A. y ≥ ... means shading is above the (solid) line

     x² < ... means shading is between (dashed) limits on x

This shading matches the graph.

__

  B. y ≤ ... means shading is below the line

     x² > ... means shading is outside limits on x (left of left limit, or right of right limit)

This shading is the reverse of that shown in the graph.

__

  C. y ≤ ... means shading is below the line

      x² < ... means shading is between limits on x

This shading matches the blue, but not the red.
