To reflect the function \( f(x) = |x| + 2 \) across the x-axis, you need to negate the entire function.
The formula for \( g(x) \) after reflecting \( f(x) \) across the x-axis is:
\[ g(x) = -f(x) \]
Since \( f(x) = |x| + 2 \), we can substitute that into the equation:
\[ g(x) = -(|x| + 2) \]
This simplifies to:
\[ g(x) = -|x| - 2 \]
So, in your case, you would insert a negative sign in front of both parts of the original function:
\[ g(x) = -|x| - 2 \]
This indicates the appropriate symbols needed to reflect the function across the x-axis. If you are asked to place symbols in \( g(x) = |x| _ 2 \), it would look like:
\[ g(x) = -|x| - 2 \] with the appropriate operations indicated.
