Sagot :

Certainly! To fill in the values of [tex]\(y\)[/tex] in the table for the given function [tex]\(y = 3x^2 - 4\)[/tex], we will evaluate the function at each specified [tex]\(x\)[/tex] value.

Let's go step by step:

1. For [tex]\( x = -2 \)[/tex]:
[tex]\[ y = 3(-2)^2 - 4 \][/tex]
[tex]\[ y = 3(4) - 4 \][/tex]
[tex]\[ y = 12 - 4 \][/tex]
[tex]\[ y = 8 \][/tex]

2. For [tex]\( x = -1 \)[/tex]:
[tex]\[ y = 3(-1)^2 - 4 \][/tex]
[tex]\[ y = 3(1) - 4 \][/tex]
[tex]\[ y = -1 \][/tex]

3. For [tex]\( x = 0 \)[/tex]:
[tex]\[ y = 3(0)^2 - 4 \][/tex]
[tex]\[ y = 0 - 4 \][/tex]
[tex]\[ y = -4 \][/tex]

4. For [tex]\( x = 1 \)[/tex]:
[tex]\[ y = 3(1)^2 - 4 \][/tex]
[tex]\[ y = 3(1) - 4 \][/tex]
[tex]\[ y = -1 \][/tex]

5. For [tex]\( x = 2 \)[/tex]:
[tex]\[ y = 3(2)^2 - 4 \][/tex]
[tex]\[ y = 3(4) - 4 \][/tex]
[tex]\[ y = 12 - 4 \][/tex]
[tex]\[ y = 8 \][/tex]

Now we can fill in the table with the calculated [tex]\(y\)[/tex] values:

[tex]\[ \begin{tabular}{|l|l|l|l|l|l|} \hline $x$ & -2 & -1 & 0 & 1 & 2 \\ \hline $y$ & 8 & -1 & -4 & -1 & 8 \\ \hline \end{tabular} \][/tex]

So, the completed table is:

[tex]\[ \begin{tabular}{|c|c|c|c|c|c|} \hline $x$ & -2 & -1 & 0 & 1 & 2 \\ \hline $y$ & 8 & -1 & -4 & -1 & 8 \\ \hline \end{tabular} \][/tex]
