    For the one where you had to translate the graph, you shifted it 3 units to the right parallel to the x axis right

    for the coodinates of intersection did you put (2, 0.21) or something
    I put x=1.9 y=0.3 as the estimate, my line wasnt the bes but I think if you are within a couple of decimal places then its fine

    Hey, how many marks would i get if i put k > -15/2, I think thst what i put so would i only lose one mark for the incorrect inequality?

    There was one where you had to find the intersection with the axis (the last question part i)

    I got something like 1,0 , 1.5,0

    and intersects y at 0,-3

    If you showed sufficient working I think you'd get all marks but one.

    I'm just going to list my answers to see if people agree with them.... (They may not be in the exact order and I may have fOr gotten some, but I will try and write down the question bit too)
    1. 3^0= 1
    9^3/2 =27
    (4/5)^-2= 25/16
    2. (1-2x)/4>3 = x>-11/2
    3. (5c^2d)^3 / (2c^4)/ d^5 = 250c^10d^-2


    4. One with intercepts of two lines x=9/7 and y=22/9
    5. Root 50 + 2root8= 11root2


    ii. Other surds question= 2+root3

    6.
    Remainder of f(2) is 11 remainder of (x+1) is 11 f(x)= x^3+ax+c
    A=-2 and c=7

    7. Expand (1-5x)^4
    1-20x+150x^2- 500x^3 + 625x^4

    8. Find minimum and then Sketch graph of (x-2)^2=9
    Minimum at (2,-9)
    Crosses x axis at -1 and 5 and y axis at -5

    Minimum at (2,-9 4 which i got y=22/7
    Crosses x axis at -1 and 5 and y axis at -5
    I got the same as that apart from for 4 where i got y=22/7

    Got wrong final answer to the last question but still used the discriminant, how many marks will i lose? 1?
    I think they give 1 or 2 marks for the discriminant.

    How many marks was the last question cos i got k <-3/2. Also how many marks dyu think i will lose for forgettting to find the point of intersection

    1-20x+150x^2- 500x^3 + 625x^4
    It said expand as simple as possible so I thought you're supposed to leave it still with the brackets

    Yes it should be y=22/7 (typo)

    Does anyone have the unofficial mark scheme? Think I messed up question 8 I got a=-10 and c=some positive fraction I can't quite remember. I thought this paper was quite hard compared to some of the other past papers I have done
