The table gives values for \(y=5x^2-x^3-4\).
| x | −2 | −1 | 0 | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|---|---|---|
| y | 24 | −4 | 8 | 14 | −4 |
(a) Complete the table. [3]
(b) Draw \(y=5x^2-x^3-4\) for \(-2\le x\le5\). [4]
(c) Draw a suitable straight line to solve \(x^3-5x^2-x+14=0\). [4]
