As the problem is posed,  worded,  printed and presented,  is is either  NONSENSE,  or  MISTAKE   (or  BOTH).


If a curve is such that   dy/dx = 2(3x + 4)^(3/2) - 6x - 8,   then  x= -1  is  NOT  a stationary point,
as it is easy to check to anybody familiar with the conception a  " stationary point ".
