extreme f(x)=(x^2(x-1))/(x+2),x\ne 2

extreme points

f (x) = \frac{x ^{2} ( x - 1 )}{x + 2}, x \neq = 2

Minimum (\frac{- 5 - 57}{4}, \frac{19 57 + 143}{8}), Maximum (0, 0), Minimum (\frac{- 5 + 57}{4}, - \frac{19 57 - 143}{8})

Solution steps

Find the critical points:

x = \frac{- 5 - 57}{4}, x = 0, x = \frac{- 5 + 57}{4}

Domain of

\frac{x ^{2} ( x - 1 )}{x + 2}, x \neq = 2 : x < - 2 or - 2 < x < 2 or x > 2

Find intervals:

Decreasing

: - \infty < x < \frac{- 5 - 57}{4},

Increasing

: \frac{- 5 - 57}{4} < x < - 2,

Increasing

: - 2 < x < 0,

Decreasing

: 0 < x < \frac{- 5 + 57}{4},

Increasing

: \frac{- 5 + 57}{4} < x < 2,

Increasing

: 2 < x < \infty

Plug the extreme point

x = \frac{- 5 - 57}{4}

into

\frac{x ^{2} ( x - 1 )}{x + 2} \Rightarrow y = \frac{19 57 + 143}{8}

Minimum (\frac{- 5 - 57}{4}, \frac{19 57 + 143}{8})

Plug the extreme point

x = 0

into

\frac{x ^{2} ( x - 1 )}{x + 2} \Rightarrow y = 0

Maximum (0, 0)

Plug the extreme point

x = \frac{- 5 + 57}{4}

into

\frac{x ^{2} ( x - 1 )}{x + 2} \Rightarrow y = - \frac{19 57 - 143}{8}

Minimum (\frac{- 5 + 57}{4}, - \frac{19 57 - 143}{8})

Minimum (\frac{- 5 - 57}{4}, \frac{19 57 + 143}{8}), Maximum (0, 0), Minimum (\frac{- 5 + 57}{4}, - \frac{19 57 - 143}{8})

f (x) = 9 x^{3} + 21 x^{2} + 8 x - 3

f (x) = x^{2} - 2 x + 5 [- 1.4]

2 x^{4} - 196 x^{2} - 3

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

f (x) = sin (3 x), - \frac{π}{4} \leq x \leq \frac{π}{3}
