To reflect the function \( f(x) = (x + 1)^2 \) over the x-axis, we need to multiply the entire function by \(-1\).
The original function is:
\[ f(x) = (x + 1)^2 \]
To find \( g(x) \), which is the reflection of \( f(x) \) over the x-axis, we have:
\[ g(x) = -f(x) = -((x + 1)^2) \]
Thus, the equation for \( g(x) \) is:
\[ g(x) = -(x + 1)^2 \]
This means that the equation for \( g(x) \) after the reflection is:
\[ g(x) = -(x + 1)^2 \]
