Edexcel A-Level Mathematics AS P1.1.12 Effect of Simple Questions

Practise Edexcel IAL Mathematics P1.1.12 by applying horizontal and vertical transformations, updating coordinates and labelling transformed graph features.

Exam points

Map key coordinates under transformations such as y = f(x − π/6) or y = −1/2f(x).
Sketch transformed graphs and label the new positions of stated points.

[Maximum number: 3]

On a separate diagram, sketch the curve with equation

y=-\frac{k}{x}+k \quad k>0 \quad x \neq 0

stating the coordinates of the point of intersection with the x-axis and, in terms of k, the equation of the horizontal asymptote.

(b) Note on EPEN it is M1B1A1. We are marking this B1ftB1B1

B1ft For attempting to translate their graph from part (a) up (or a correct graph if (a) is incorrect)

B1 For a correct intercept stated (or allow $1, \frac{k}{k}$ or (1,0) marked on the correct axis with the curve passing through this) OR y=k stated. Do not allow just k to be marked on the line of the asymptote.

B1 For a correct intercept stated (or allow $1, \frac{k}{k}$ or (1,0) marked on the correct axis with the curve passing through this) AND y=k stated. Do not allow just k to be marked on the line of the asymptote.

Note if they have a contradiction between what is stated and what is written on the graph then the graph takes precedence.
