Given: y = x^3  3x^2 + 2 Therefore: dy/dx = 3x^2  3*2x = 3x(x  2) Equating above expression for dy/dx to 0, we get two values of x. x 1 = 0 and x2 = 2 To get corresponding value of function, we substitute these values of y in equation for y. Thus: y1 = 0^3  3*0^2 + 2 = 2 y2 = 3^3  3*2^2 + 2 = 27  12 + 2 = 17 Answer: Maximum = 17 Minimum = 2
