(2)
| \(x\) | \(-2\) | \(-1\) | 0 | 1 | 2 | 3 |
|---|---|---|---|---|---|---|
| \(y\) | 4 | \(-2\) |
(b) On the grid, draw the graph of \(\ y = x^2 - x - 2\ \) for values of \(x\) from \(-2\) to 3
| Answer | Mark | Mark scheme |
|---|---|---|
| (4) 0 −2 (−2) 0 4 | B2 | for all 4 correct values |
| (B1 | for 2 or 3 correct values) |
