Copy and complete the table of values for [tex]\( y = x^2 + 6 \)[/tex]. What numbers replace [tex]\( A \)[/tex] and [tex]\( B \)[/tex]?

[tex]\[
\begin{tabular}{c||r|c|c|c|c}
x & -2 & -1 & 0 & 1 & 2 \\

Let's determine the values of [tex]\( A \)[/tex] and [tex]\( B \)[/tex] in the table for the equation [tex]\( y = x^2 + 6 \)[/tex].

We'll plug in the given [tex]\( x \)[/tex]-values into the equation [tex]\( y = x^2 + 6 \)[/tex], and compute the corresponding [tex]\( y \)[/tex]-values.

1. For [tex]\( x = -2 \)[/tex]:
[tex]\[ y = (-2)^2 + 6 = 4 + 6 = 10 \][/tex]
So, [tex]\( A \)[/tex] is 10.

2. For [tex]\( x = -1 \)[/tex]:
[tex]\[ y = (-1)^2 + 6 = 1 + 6 = 7 \][/tex]

3. For [tex]\( x = 0 \)[/tex]:
[tex]\[ y = 0^2 + 6 = 0 + 6 = 6 \][/tex]

4. For [tex]\( x = 1 \)[/tex]:
[tex]\[ y = 1^2 + 6 = 1 + 6 = 7 \][/tex]

5. For [tex]\( x = 2 \)[/tex]:
[tex]\[ y = 2^2 + 6 = 4 + 6 = 10 \][/tex]
So, [tex]\( B \)[/tex] is 10.

Based on these computations, the completed table of values for [tex]\( y = x^2 + 6 \)[/tex] is:
[tex]\[ \begin{tabular}{c||r|c|c|c|c} $x$ & -2 & -1 & 0 & 1 & 2 \\ \hline $y$ & 10 & 7 & 6 & 7 & 10 \\ \end{tabular} \][/tex]

Therefore, the numbers that replace [tex]\( A \)[/tex] and [tex]\( B \)[/tex] are both 10.
