Answer 1

Answer:

$\begin{array}{| c | c | c |c| c| c | c| c |}\cline{1-8} x & - 3 & - 2 & - 1 & 0& 1 & 2 & 3\\\cline{1-8} y & 6 &\textbf{0} &\textbf{ - 4} & - 6 & \textbf{ - 6}& \textbf{ - 4}& \textbf{0} \\\cline{1-8}\end{array}$

Step-by-step explanation:

The 2nd column of the table means that when x= -3, y= 6.

Since this table of values is for the equation of y= x² -x -6,

substitute the given values of x into the equation to find the respective values of y.

3rd column:

y= x² -x -6

When x= -2,

y= (-2)² -(-2) -6

y= 4 +2 -6

y= 0

4th column:

y= x² -x -6

When x= -1,

y= (-1)² -(-1) -6

y= 1 +1 -6

y= -4

6th column:

y= x² -x -6

When x= 1,

y= 1² -1 -6

y= 1 -1 -6

y= -6

7th column:

y= x² -x -6

y= 2² -2 -6

y= 4 -2 -6

y= -4

8th column:

y= x² -x -6

y= 3² -3 -6

y= 9 -3 -6

y= 0
