Find the x-coordinates of the stationary points on the graph with equation f(x)= x^3 + 3x^2 - 24x
This answer has 3 steps:1) find the derivative, f’(x), of the function2) factorise the derivative 3) set equal to zero and solve for x1) f’(x) = 3x^2 + 6x - 242)f’(x) = 3(x^2 + 2x - 8)3) x^2 + 2x - 8 = 0 (x+4)(x-2)=0x = -4 x = 2
