Answer:
<h2>B) x² - 4</h2>Step-by-step explanation:
f(x) + n - shift the graph n units up
f(x) - n - shift the graph n units down
f(x + n) - shift the graph n units to the left
f(x - n) - shift the graph n units to the right
------------------------------------------------------------------------------
The vertex of the function f(x) = x² is in the origin.
We have the vertex (0, -4). Therefore, the graph has been moved by 4 units down.
f(x) - 4 = x² - 4
