    What transformation describes 0.5f(x+1)

    The mark scheme says Translate 1 to the left and then a Y stretch of 0.5

    Is this the same as Y stretch of 0.5 then translate 1 the left?

    Yes because one affects Y values and the other one X values only so the order does not matter..but if it was 0.5f(x)+3 then the order would matter.

    In that case would you do the stretch then the translation? Just realised I don't actually know.

    Yes, however, if it is f(2x+6) then you translate first then multiply by 1/2 scale factor. Or you pull 2 out getting f(2(x+3) ) , multiply then stretch.
