(2)
| \(x\) | −2 | −1 | 0 | 1 | 2 | 3 | 4 |
|---|---|---|---|---|---|---|---|
| \(y\) | 0 | −3 |
(b) On the grid, draw the graph of \(y = x^2 - 2x - 3\) for values of \(x\) from \(-2\) to 4
| Answer | Mark | Mark scheme |
|---|---|---|
| \(5, (0), -3, -4, (-3), 0, 5\) | B2 | for all 5 correct values |
