y = (x+4)(6x-7). By differentiating, find the x coordinate of the maximum of this equation.

y=(x+4)(6x-7)y=6x2+17x-28dy\dx = 12x + 17To find the x coordinate of the stationary points of y, let dy\dx=012x+17=0x=-17\12

f(x) = 2x^3+6x^2-18x+1. For which values of x is f(x) an increasing function?


Given y=x^3-x^2+6x-1, use diffferentiation to find the gradient of the normal at (1,5).


f(x) = 3x^3 – x^2 – 20x – 12 (a) Use the factor theorem to show that (3x + 2) is a factor of f(x). [2 marks] (b) Factorise f(x) fully. [3 marks]
