Evaluate the function [tex]$g(x) = -2x^2 + 3x - 5$[/tex] for the input values [tex]-2, 0[/tex], and [tex]3[/tex].

[tex]\[
\begin{array}{l}
g(-2) = -2(-2)^2 + 3(-2) - 5 \\
g(-2) = -2(4) - 6 - 5 \\
g(-2) = -19
\end{array}
\][/tex]

[tex]\[
g(0) = \square
\][/tex]

[tex]\[
g(3) = \square

To evaluate the function [tex]\( g(x) = -2x^2 + 3x - 5 \)[/tex] for the input values [tex]\(-2\)[/tex], [tex]\(0\)[/tex], and [tex]\(3\)[/tex], we follow these steps:

1. Evaluate [tex]\( g(-2) \)[/tex]:
[tex]\[ \begin{array}{l} g(-2) = -2(-2)^2 + 3(-2) - 5 \\ g(-2) = -2(4) + (-6) - 5 \\ g(-2) = -8 - 6 - 5 \\ g(-2) = -19 \end{array} \][/tex]

2. Evaluate [tex]\( g(0) \)[/tex]:
[tex]\[ \begin{array}{l} g(0) = -2(0)^2 + 3(0) - 5 \\ g(0) = 0 + 0 - 5 \\ g(0) = -5 \end{array} \][/tex]

3. Evaluate [tex]\( g(3) \)[/tex]:
[tex]\[ \begin{array}{l} g(3) = -2(3)^2 + 3(3) - 5 \\ g(3) = -2(9) + 9 - 5 \\ g(3) = -18 + 9 - 5 \\ g(3) = -14 \end{array} \][/tex]

Thus, the evaluated values are:

[tex]\[ g(-2) = -19,\, g(0) = -5,\, g(3) = -14 \][/tex]

So in the format that the question asks for, we fill in the squares as follows:

[tex]\[ \begin{array}{l} g(-2) = -19 \\ g(0) = -5 \\ g(3) = -14 \end{array} \][/tex]
