Quizplus · Accepted Answer

Using point-by-point plotting, we choose various values of x and find the corresponding y values, then plot the points on a graph and connect them with a smooth curve. For this equation, we can use the following table to find points:

| x | y |
|---|---|
| -2 | -10 |
| -1 | -1 |
| 0 | 0 |
| 1 | -1 |
| 2 | -10 |

Plotting these points and connecting them with a smooth curve results in the graph shown in choice B.
