(a) Find the gradient of the following functions at the given point. (i) y = 3t-6 – 2t2 +t+1 when t=1 (3 marks) (ii) y = 3cos(50) - e20 when @ = 0 (3.5 marks) 5 (ii) y = x - x2 when x = 8 (5.5 marks) (b) Given the function, f(x) = x3 - 12x +1. (i) Find the location and nature of the stationary points. (7 marks) Find the interval/s in which f(x) is increasing and the intervals in which f(x) is decreasing (ii)
