1. The curve C has equation y = 3x^4 – 8x^3 – 3 (a) Find (i) d d y x (ii) d d 2 y x 2 (3) (b) Verify that C has a stationary point when x = 2 (2) (c) Determine the nature of this stationary point, giving a reason for your answer.

To differentiate use formula. multiply factor by power then minus one from power (where x is invloved) dy/dx = 12x^3 - 24x^2 d^2y/dx^2 = 36x^2 - 48x (this is just a further differentiation) b) to find statio...
