extreme x(sqrt(8-x^2))

extreme points

x (8 - x^{2})

Maximum (- 22, 0), Minimum (- 2, - 4), Maximum (2, 4), Minimum (22, 0)

Solution steps

Find the critical points:

x = - 22, x = - 2, x = 2, x = 22

Domain of

x 8 - x^{2} : - 22 \leq x \leq 22

Find intervals:

Decreasing

: - 22 < x < - 2,

Increasing

: - 2 < x < 2,

Decreasing

: 2 < x < 22

Plug the extreme point

x = - 22

into

x 8 - x^{2} \Rightarrow y = 0

Maximum (- 22, 0)

Plug the extreme point

x = - 2

into

x 8 - x^{2} \Rightarrow y = - 4

Minimum (- 2, - 4)

Plug the extreme point

x = 2

into

x 8 - x^{2} \Rightarrow y = 4

Maximum (2, 4)

Plug the extreme point

x = 22

into

x 8 - x^{2} \Rightarrow y = 0

Minimum (22, 0)

Maximum (- 22, 0), Minimum (- 2, - 4), Maximum (2, 4), Minimum (22, 0)

f (x) = f (x) = - 8 x^{2} - 144 x + 6

f (x) = x^{3} - 3 x [0.3]

f (x) = \frac{4860}{x} + 18 x + 731856

f (x) = 3 x^{2} + 4 x - 6

f (x, y) = (x - 3)^{2} - (y - 1)^{2}
