the turning point it the vertex of the parabola aka the stationary point. you can use calculus to get that point by solving f'(x) = 0 or alternatively the coordinates will be (-b/2a, f(-b/2a) )
to show it is a max; show f''(-b/2a) < 0
yeah something on young offenders or maybe a theme for crime.
Family/other topics: almost always a contemporary issue/s and maybe some discussion of something else
understanding the process will not get you a higher mark. 1.7% is pretty much negligable
assessment/exam mark for rank 1: 94/80 = final mark of ~87
assessment/exam mark for rank 2: 80/94 = final mark of ~87
alright; I'll give you what I would do for the question. prove each angle is 90 degrees and show that 2 of the sides are equal hence the other 2 are equal and hence it much be a square.
and it is only 2 marks so imo I would just skip it
just put that as the rep comment ;)
