Which of the following can represent the curve x² = −2y
A
B
C
D
Explanation
The equation x² = −2y can be written as y = −(1/2)x². This is a parabola with vertex at the origin and it opens downward along the negative y-axis. The graph is symmetric about the y-axis and curves downward from the origin. Hence the correct representation is graph (d).
