    I am not doing OCR but i can help you on Q.10.
    Differentiate the equation to get dy/dx , then plug in the value of x. Solve from there.

    For q 10 take dy/dx once you get that sub x=1 in place of x and you will see that dy/dx (the gradient) will come to a value of minus five

    Question 7ia.) is y = 2f(x) so it means a y stretch therefore you must multiply all y values by 2 and keep the x values the same.

    Question 7ib.) y = f(x-1) means you are moving the whole graph to the right therefore you must keep the y values constant and change the xvalues accordingly

    No it's just a rule of the forums. We don't give the full solutions - instead we help the OP to get there

    Whatever it is, if it gives the answer without them doing any work or with them being led straight to the final calculation or something, it's probably best you leave it.

    The point of this forum isn't to just give the answers, it's not helpful to learn from something you're struggling with by just getting the answer. It's much more helpful getting assistance on how to get to the answer, that way you know how to do it the next time you're in a pickle.

    I didn't realise That sucks. Oh well good to get the practice in by doing it yourself.

    At the end of the day though it's up to the OP if she wants to actually learn from the worked solutions.

    Thanks for the tag, Student403.

    This one is a bit of a weird case, as the OP isn't even bothering to show her working or ask for help - but yeah, full solutions are against the forum guidelines because we feel that it's much better to help the OP reach an answer and prod her along using hints so that she grows from the experience mathematically.

    I'll kindly ask the OP to clarify what troubles she's having and to show her working.

    She probably does if she's asking for help.
