    Question 1.i and 2.i and 2.ii
    Question 1i) This is just a simple case of composition of functions. You may be used to this notation:  f^2 (x) or  ff(x)

    Question 2i) The question states that this graph has two stationary points, or in other words, those two points lie on the graph. So, sub both points into your function and you may realise something.

    Question 2ii) Simple, assuming you're able to find a and b.
