      I was also thinking the same. I think he made a mistake, it's not the first time.
      The answer is (-infinity ; 1)

      use the formula y = a (x - x1)(x - x2). you use this only when they give a point and the two x intercepts. in q6 they give u a point D(1;8) but don't give you the values of the x intercepts. if they did give u, you'd substitute like this 8 = a (1 - x1)(1 - x2). x1 and x2 would be where your two different intercepts go. then you solve for a and substitute it back into formula to the equation of the actual graph then you get your b value from there

      Basically what I did is that I made an equation for c, solved for b which you do by making x(turnib point) = -b/2a and then substitute b into c equation to get c....fairly easy

    Refering to question 5.3 , is it correct if i factorized x^2 - 2x - 8 = 0 ( from 2x^2 - 4x - 16 = 0 ) into ( x - 4 )( x + 2 )
