Jawaban:

f(x)=x^3-6x²+9x+5

f'(x)=3x²-12x+9

(3x-3)(x-3)

3x-3=0 x-3=0

3x =3 atau x2 =3

x =3/3

x1 =1

x1=1 disubtitusikan ke f(x)=x^36x²+9x+5

f(x)=x^3-6x²+9x+5

=(1)^3-6(1)²+9(1)+5

=1-6(1)+9+5

=1-6+14

=9

x2=3 disubtitusikan ke f(x)=x^3-6x²+9x+5

f(x)=x^3-6x²+9x+5

=(3)^3-6(3)²+9(3)+5

=27-6(9)+27+5

=27-54+27+5

=5

nilai maksimum(nilai tertinggi)=9

nilai minimum(nilai terendah)=5

Semoga membantu
