extreme f(x)=2x^3+9x^2-60x+7,-5<= x<= 5

extreme

Maximum (- 5, 282), Minimum (2, - 61), Maximum (5, 182)

Solution steps

Find the critical points:

x = - 5, x = 2, x = 5

Domain of

2 x^{3} + 9 x^{2} - 60 x + 7, - 5 \leq x \leq 5 : - 5 \leq x \leq 5

Find intervals:

Decreasing

: - 5 < x < 2,

Increasing

: 2 < x < 5

Plug the extreme point

x = - 5

into

2 x^{3} + 9 x^{2} - 60 x + 7 \Rightarrow y = 282

Maximum (- 5, 282)

Plug the extreme point

x = 2

into

2 x^{3} + 9 x^{2} - 60 x + 7 \Rightarrow y = - 61

Minimum (2, - 61)

Plug the extreme point

x = 5

into

2 x^{3} + 9 x^{2} - 60 x + 7 \Rightarrow y = 182

Maximum (5, 182)

Maximum (- 5, 282), Minimum (2, - 61), Maximum (5, 182)

What is the extreme f(x)=2x^3+9x^2-60x+7,-5<= x<= 5 ?
The extreme f(x)=2x^3+9x^2-60x+7,-5<= x<= 5 is Maximum(-5,282),Minimum(2,-61),Maximum(5,182)
