To determine the output of the given function [tex]\( F(x) = -x^3 - 2x^2 + 7x - 10 \)[/tex] for [tex]\( x = 1 \)[/tex], follow these steps:

1. Substitute [tex]\( x = 1 \)[/tex] into the function [tex]\( F(x) \)[/tex]:
[tex]\[ F(1) = - (1)^3 - 2(1)^2 + 7(1) - 10 \][/tex]

2. Calculate each term:
[tex]\[ (1)^3 = 1 \][/tex]
[tex]\[ 2(1)^2 = 2 \][/tex]
[tex]\[ 7(1) = 7 \][/tex]

3. Substitute these values back into the equation:
[tex]\[ F(1) = -1 - 2 + 7 - 10 \][/tex]

4. Perform the arithmetic operations step by step:
[tex]\[ -1 - 2 = -3 \][/tex]
[tex]\[ -3 + 7 = 4 \][/tex]
[tex]\[ 4 - 10 = -6 \][/tex]

Therefore, the output of the function [tex]\( F(x) = -x^3 - 2x^2 + 7x - 10 \)[/tex] for [tex]\( x = 1 \)[/tex] is:
[tex]\[ \boxed{-6} \][/tex]
