yeah let's do it.AB root13integral 4x^3 -2/3x^-2 -2/9x^-3 - 24co-ords of normals B and C were ( -4,y) correct if wrong where y = 12/x 5 and parallel to 4y = 3x cb^2-4ac < 0 therefore no real rootsinequality was easy but cant rememberd = 12 leading to u17 which i can't remember, 108?final question transformations, stretch by2, translate 2 units left (find where cross y) and k = -4 a = 0please add/change if im wrong i need to know if i got an a in maths im worried now :s

I got t as 7/4 and area as 39/8
For c I think I got 8/9
The coordinates of B were like 3,9 and c -3,1
What did everyone get for a I got 1 and then k -4
For the f(x+2) was the y intercept 2 also.
For the inequality one I got for the final inequality -1/2<x<1/3
How did you find the coordinates and the constant a and k?
