Question 23 • 25-26 TX-Precalculus B

Which statement describes the graph of y + 2 ≥ –4(x – 3)2?

Answer
A
a parabola opening up, with shading above the vertex
B
a parabola opening up, with shading below the vertex
C
a parabola opening down, with shading above the vertex
D
a parabola opening down, with shading below the vertex

Explanation

Rewrite the inequality as y ≥ −4(x − 3)² − 2. The negative coefficient −4 means the parabola opens downward, and because y is greater than or equal to the expression, the region above the parabola is shaded. This matches “a parabola opening down, with shading above the vertex.”
