iv) if you use differentiation, you can find out the maximum point when dy/dx = 0. Alternatively, solve it by completing the square in the form y = a(x-h)+b.
*Common mistake: note that in this case since k is given in the question, it is not y=a(x-h)+k, since the constants are not the same as the one given in the question; b has to be found via your working.
