We are given the function $$ g(x) = -x^2 + 2x + 4 $$.

1. Substitute $$ x = 9 $$ into the function:
   $$
   g(9) = -(9)^2 + 2(9) + 4
   $$

2. Compute the square:
   $$
   = -81 + 18 + 4
   $$

3. Combine the terms:
   $$
   = -81 + 22 = -59
   $$

Thus, $$ g(9) = -59 $$.
$$ g(9) = -59 $$

Let \( g(x)=-x^{2}+2 x+4 \). Find \( g(9) \). \( g(9)=\square \) (Simplify your answer. Type an integer or a fraction.)
