The correct response is:
B. the y-intercept
The y-intercept of the graph of \( y = x^2 \) is 0 (when \( x = 0 \)). If the graph has been moved down 3 units, the new equation would be \( y = x^2 - 3 \), which means the y-intercept is now -3. This clearly illustrates that the graph has been moved down by 3 units.
