A1 63/65
A2 (a) A(1,4) (b) graph moves 2 left and 4 up so (0,0)-->(-2,4); A(1,4)-->(-1,8); B(3,0)-->(1,4) (c) 4<k<8
A3 a = 30
A4 (a) (i) x = 1/3 and x = 3 (ii) when x=1/3 y-coordinates are not equal: gap between curves; when x=3 both y-coordinates are -8: this is point B (b) Area = 64/3
A5 a = 3/5 and limit = 25
A6 For all real values of k

A1 (a) y = -x + 1 (b) (-1,-6)
A2 (a) 2y + x = 9 (b) (x-1)2 + (y-4)2 = 25 (c) (i) y = 9 (ii) T(-9,9)
A3 (a) p(x) = 3 - 3/x (b) p(q(x)) = x
A4 (a) y = -x(x-4) (b) proof
