2. (6 points) Find the critical point(s) (if any) of a continuous function f(x) if BROS X f(x) = 1 -12 - 121 F(x )=3x2-12x x4 + 1 g(x ) = x4+ 1 Justify your answer. (3x2-2x-12)(x4+1 )-(x -x3-12x)(4x3)/ F'( x ) = 3x8- 2 x- 12 g' ( x )= 4x3 3*6 - 2x5-12x4+3x-X-11 N C (x 4 + 1)2 Guest578 X = X CP(s) at 1 =_
