extreme f(x)=x^3-x^2-8x+8,-2<= x<= 0

extreme

Minimum (- 2, 12), Maximum (- \frac{4}{3}, \frac{392}{27}), Minimum (0, 8)

Solution steps

Find the critical points:

x = - 2, x = - \frac{4}{3}, x = 0

Domain of

x^{3} - x^{2} - 8 x + 8, - 2 \leq x \leq 0 : - 2 \leq x \leq 0

Find intervals:

Increasing

: - 2 < x < - \frac{4}{3},

Decreasing

: - \frac{4}{3} < x < 0

Plug the extreme point

x = - 2

into

x^{3} - x^{2} - 8 x + 8 \Rightarrow y = 12

Minimum (- 2, 12)

Plug the extreme point

x = - \frac{4}{3}

into

x^{3} - x^{2} - 8 x + 8 \Rightarrow y = \frac{392}{27}

Maximum (- \frac{4}{3}, \frac{392}{27})

Plug the extreme point

x = 0

into

x^{3} - x^{2} - 8 x + 8 \Rightarrow y = 8

Minimum (0, 8)

Minimum (- 2, 12), Maximum (- \frac{4}{3}, \frac{392}{27}), Minimum (0, 8)

What is the extreme f(x)=x^3-x^2-8x+8,-2<= x<= 0 ?
The extreme f(x)=x^3-x^2-8x+8,-2<= x<= 0 is Minimum(-2,12),Maximum(-4/3 , 392/27),Minimum(0,8)
