Higher November 2024 Paper 1 Q23
23 In each part, the graph shown is a transformation of the graph \(\quad y = x^2\)
(a) Write down the equation of the graph shown. [1 mark]
(b) Write down the equation of the graph shown. [1 mark]
(c) Write down the equation of the graph shown. [1 mark]
| Answer | Mark | Comments |
|---|---|---|
| \(y = x^2 + 2\) | B1 | oe equation eg \(y - 2 = x^2\) |
Additional guidance
In (a), (b) and (c), on otherwise correct answers only withhold the mark for the first missing \(y =\)
| Answer | Mark | Comments |
|---|---|---|
| \(y = -x^2\) | B1 | oe equation eg \(y + x^2 = 0\) |
Additional guidance
In (a), (b) and (c), on otherwise correct answers only withhold the mark for the first missing \(y =\)
| Answer | Mark | Comments |
|---|---|---|
| \(y = (x - 3)^2\) | B1 | oe equation eg \(y = x^2 - 6x + 9\) |
Additional guidance
| In (a), (b) and (c), on otherwise correct answers only withhold the mark for the first missing \(y =\) | |
| Ignore an incorrect expansion after the correct equation is seen | B1 |
