Graph Transformations : C1 Edexcel June 2012 Q10
Figure 1 shows a sketch of the curve C with equation y = f(x) where
f(x) = x2(9 – 2x)
There is a minimum at the origin, a maximum at the point (3, 27) and C cuts the x-axis at the point A.
(a) Write down the coordinates of the point A.
(b) On separate diagrams sketch the curve with equation
(i) y = f(x + 3)
(ii) y = f(3x)
On each sketch you should indicate clearly the coordinates of the maximum point and any points where the curves cross or meet the coordinate axes.
The curve with equation y = f(x) + k, where k is a constant, has a maximum point at (3, 10).
(c) Write down the value of k
