To determine the x-intercepts of the function that translates the original function \( f(x) = x^2 \) down 4 units, we first need to write the new function.
The function translated down 4 units is:
\[
f(x) = x^2 - 4
\]
Next, we find the x-intercepts by setting \( f(x) = 0 \):
\[
x^2 - 4 = 0
\]
We can solve this equation as follows:
\[
x^2 = 4
\]
\[
x = \pm 2
\]
Thus, the x-intercepts are \( x = -2 \) and \( x = 2 \).
The correct response is:
**x equals negative 2 and x equals 2.**
