The Mathematics P1 Grade 12 September was written on Friday, 15 September 2017. We were made aware of certain amendments and omissions that were discovered during the marking process.
In order to address this and to ensure that learners are not disadvantaged, the following standardised approach to marking must be adopted across the Province. The following guidelines with regard to marking was prepared in conjunction with the examiner and moderator.
| 5.5 | P (−3 / 2; −9 / 4) f(x - 2) = (x - 2)(x - 2 + 3 ) | ✔✔ answer ✔f(x - 2) = x2 - x - 2 ✔x = 1 / 2 (2) |
6.2 | q(x) = -2-x | ✔ answer(1) |
6.4 | y> 0 ; y ∈ R | (1) |
6.5 | See 6.1 | ✔✓ shape and x-intercept(2) |
10.2 | V = 2x × x × (81 − 2x ) V = 81x −4/3xa | ✔✓ sub. into volume formula (2) |
10.3 | dV = 81 - 4x2 4 x = 9/2 = 4.5 | ✔81 - 4x2 ✔x2 = 81 ✔answer(3) |
