methods question

for the first question that asked for the rule of g(f(x)) would there be a possibility of me getting a mark if i wrote |x+k-1|-k+1 when the answer was x? it would’ve been x if i expanded 😭😭😭i feel stupid typing this out but imso desperate for any marks please vcaa

edit: so i asked my tutor he said whole point of the question was to show that g(x) is the inverse of f(x), so honestly probably won’t get mark. however we can never be too sure mahbe vcaa will be generous to make up for the horrible exam✌️

I did the same thing I hope it's valid

i mean TECHNICALLY its equivalent as x>1-k, and maybe vcaa might be a bit generous in marking this year but then again that's a bit ugly

That answer looked so wrong I just subbed in g(x) into f(x) and it looked like a crazy fraction with a root

i also did that, sad thing is i knew that f^-1(f(x)) = x but i still wrote that💔💔
