To find the x-intercept(s) of the function that translates the original function \( f(x) = x^2 \) down 4 units, we first need to determine the new function after the translation.

The original function is: \[ f(x) = x^2 \]

Translating it down by 4 units gives: \[ g(x) = f(x) - 4 = x^2 - 4 \]

Next, we find the x-intercepts of the function \( g(x) \) by setting it equal to zero: \[ g(x) = 0 \implies x^2 - 4 = 0 \]

This can be factored: \[ (x - 2)(x + 2) = 0 \]

Setting each factor to zero gives: \[ x - 2 = 0 \quad \text{or} \quad x + 2 = 0 \] \[ x = 2 \quad \text{or} \quad x = -2 \]

Thus, the x-intercepts of the function \( g(x) = x^2 - 4 \) are: \[ x = -2 \quad \text{and} \quad x = 2 \]

The correct response is: x = -2 and x = 2.
