i think i know how to get the max and min
max=root2 which occurs when (root2)sin(x-pi/4)=root2
is that right? can somebody please tell me how to do the rest of the question and correct me if the max is wrong thank you! x

You will still have to work out the minimum value (min = - 2)
and where it cuts the x and y axis (x=0, y=0)
Then the fun part... drawing it! OMG I cant draw graphs to save myself!
