extreme f(x)=(x^3)/(x^2+1)

extreme points

f (x) = \frac{x ^{3}}{x ^{2} + 1}

Saddle (0, 0)

Solution steps

Find the critical points:

x = 0

Domain of

\frac{x ^{3}}{x ^{2} + 1} : - \infty < x < \infty

Find intervals:

Increasing

: - \infty < x < 0,

Increasing

: 0 < x < \infty

Plug the extreme point

x = 0

into

\frac{x ^{3}}{x ^{2} + 1} \Rightarrow y = 0

Saddle (0, 0)

f (x) = x^{9}

(- 1, 2), (7, - 6)

f (x) = - x^{3} + 27 x - 54

f (x) = \frac{4 x + 8}{3 x + 4}

f (x) = 5 - x + 10
