Titik stasioner : straight f apostrophe left parenthesis straight x right parenthesis equals 0 

table attributes columnalign right center left columnspacing 0px end attributes row cell straight f left parenthesis straight x right parenthesis end cell equals cell straight x cubed minus 6 straight x squared plus 4 straight x minus 5 end cell row cell straight f apostrophe left parenthesis straight x right parenthesis end cell equals cell 3 straight x squared minus 12 straight x plus 4 end cell row 0 equals cell 3 straight x squared minus 12 straight x plus 4 end cell row cell straight x subscript 1 comma 2 end subscript end cell equals cell fraction numerator negative straight B plus-or-minus square root of straight B squared minus 4 times straight A times straight C end root over denominator 2 times straight A end fraction end cell row blank equals cell fraction numerator 12 plus-or-minus square root of left parenthesis negative 12 right parenthesis squared minus 4 times 3 times 4 end root over denominator 2 times 3 end fraction end cell row blank equals cell fraction numerator 12 plus-or-minus square root of 144 minus 48 end root over denominator 6 end fraction end cell row blank equals cell fraction numerator 12 plus-or-minus square root of 96 over denominator 6 end fraction end cell row blank equals cell fraction numerator 12 plus-or-minus square root of 16 times 6 end root over denominator 6 end fraction end cell row blank equals cell fraction numerator 12 plus-or-minus 4 square root of 6 over denominator 6 end fraction end cell row blank equals cell 2 plus-or-minus 2 over 3 square root of 6 end cell row blank equals cell 2 plus-or-minus 2 over 3 left parenthesis 2 comma 45 right parenthesis end cell row blank equals cell 2 plus-or-minus 1 comma 63 end cell row cell straight x subscript 1 end cell equals cell 2 plus 1 comma 63 end cell row blank equals cell 3 comma 63 end cell row cell straight x subscript 2 end cell equals cell 2 minus 1 comma 63 end cell row blank equals cell 0 comma 37 end cell end table 

Untuk x equals 3 comma 63 maka :

table attributes columnalign right center left columnspacing 0px end attributes row cell straight f left parenthesis straight x right parenthesis end cell equals cell straight x cubed minus 6 straight x squared plus 4 straight x minus 5 end cell row cell straight f left parenthesis 3 comma 63 right parenthesis end cell equals cell left parenthesis 3 comma 63 right parenthesis cubed minus 6 left parenthesis 3 comma 63 right parenthesis squared plus 4 left parenthesis 3 comma 63 right parenthesis minus 5 end cell row blank equals cell 47 comma 83 minus 6 left parenthesis 13 comma 17 right parenthesis plus 14 comma 52 minus 5 end cell row blank equals cell 47 comma 83 minus 79 comma 02 plus 14 comma 52 minus 5 end cell row blank equals cell negative 21 comma 67 end cell end table 

Untuk x equals 0 comma 37 maka :

table attributes columnalign right center left columnspacing 0px end attributes row cell straight f left parenthesis straight x right parenthesis end cell equals cell straight x cubed minus 6 straight x squared plus 4 straight x minus 5 end cell row cell straight f left parenthesis 0 comma 37 right parenthesis end cell equals cell left parenthesis 0 comma 37 right parenthesis cubed minus 6 left parenthesis 0 comma 37 right parenthesis squared plus 4 left parenthesis 0 comma 37 right parenthesis minus 5 end cell row blank equals cell 0 comma 05 minus 6 left parenthesis 0 comma 14 right parenthesis plus 1 comma 48 minus 5 end cell row blank equals cell 0 comma 05 minus left parenthesis 0 comma 84 right parenthesis plus 1 comma 48 minus 5 end cell row blank equals cell negative 4 comma 31 end cell end table 

Jadi, Titik stasioner f left parenthesis x right parenthesis equals x cubed minus 6 x squared plus 4 x minus 5  adalah left parenthesis 3 comma 63 space comma space minus 21 comma 67 right parenthesis  dan left parenthesis 0 comma 37 space comma space minus 4 comma 31 right parenthesis.

Oleh karena itu, Tidak ada jawaban yang benar pada opsi.
