Question 1
Paper 2, calculatorMedium7 marksFigure 1 shows the graph of for
The graph of is obtained from the graph of by reflecting it in the -axis, applying a vertical stretch with scale factor and then translating it unit upwards.
(a)[1]
Write down
(b)[2]
On the same axes as Figure 1, sketch the graph of Mark the image of the point on for which
(c)[2]
Using Figure 1, determine all values of for which
(d)[2]
For the point on determine its image ordinate if the translation upwards by unit is performed after the reflection but before the vertical stretch. Hence state whether this order of transformations gives the same graph as
