(a) Complete the table of values for \(y = 6x - x^3\)
(2)
| \(x\) | \(-3\) | \(-2\) | \(-1\) | 0 | 1 | 2 | 3 |
|---|---|---|---|---|---|---|---|
| \(y\) | 9 | 4 | \(-9\) |
(b) On the grid, draw the graph of \(y = 6x - x^3\) for values of \(x\) from \(-3\) to 3
| Answer | Mark | Mark scheme |
|---|---|---|
| (9), −4, −5, 0, 5, (4), (−9) | B2 | for all 4 values correct |
| (B1 | for 2 or 3 correct values) |
