1. The diagram shows the graph of y = f(x), which consists of the two straight lines AB and BC. The lines A′B′ and B′C′ form the graph of y = g(x), which is the result of applying a sequence of two transformations, in either order, to y = f(x). State fully the two transformation.
2. The function f is defined by f(x) = x2 − 6x + c, where c is a constant. It is given that f(x) > 2 for all values of x. Find the set of possible values of
3. (a) Give the complete expansion of (x + 2/x)5.
4. Show that the equation
5. A circle has equation (x − 1)2 + (y + 4)2 = 40. A line with equation y = x − 9 intersects the circle at points A and B.
(a) Find the coordinates of the two points of intersection.
