The original function is \(y = 2x^2\), which has its vertex at (0, 0).
To move the vertex to (0, -4), we need to shift the entire graph down by 4 units. This can be accomplished by subtracting 4 from the function:
\[ y = 2x^2 - 4 \]
So, the correct equation that models this transformation is:
\[ y = 2x^2 - 4 \]
Among the provided options, the correct response is:
y = 2x² − 4
