26 Here is the graph of \(\quad y = 0.5x^2 - 6x + 12\)
| Answer | Mark | Comments |
|---|---|---|
| \((x =)\ [2.25, 2.75]\) and \((x =)\ [9.25, 9.75]\) | B2 | B1 \((x =)\ [2.25, 2.75]\) or \((x =)\ [9.25, 9.75]\) or one or both values identified but not given in correct notation eg (2.5, 0) and/or (9.5, 0) or \(2.5 \lt x \lt 9.5\) or 2.5 and/or 9.5 written on the graph or in working |
Additional guidance
| \(x =\) can be \(x \approx\) | |
| [2.25, 2.75] and/or [9.25, 9.75] with one extra value | B1 |
| [2.25, 2.75] and/or [9.25, 9.75] with more than one extra value | B0 |
| Answer from use of formula or completing the square | B0 |
