a) Curve C has equation y = 3x4 + 32x3 + 120x + 192x + 120. Find dy dx b) Divide your answer to part a) by (x+2) and hence show that written as c(x+2)2(x+4) where c is to be found. c) i) Find the coordinates of the stationary values on curve C. can be dx ii) For each stationary value, use calculus to determine if it is a maximum, a minimum or a point of inflexion. a) Curve C has equation y = 3x4 + 32x3 + 120x + 192x + 120.
