extreme f(x)=(x-4)/(3x-x^2)

extreme points

f (x) = \frac{x - 4}{3 x - x ^{2}}

Maximum (2, - 1), Minimum (6, - \frac{1}{9})

Solution steps

f^{'} (x) = \frac{x ^{2} - 8 x + 12}{( 3 x - x ^{2} ) ^{2}}

Find intervals:

Increasing

: - \infty < x < 0,

Increasing

: 0 < x < 2,

Decreasing

: 2 < x < 3,

Decreasing

: 3 < x < 6,

Increasing

: 6 < x < \infty

Plug

x = 2

into

\frac{x - 4}{3 x - x ^{2}} : - 1

Maximum (2, - 1)

Plug

x = 6

into

\frac{x - 4}{3 x - x ^{2}} : - \frac{1}{9}

Minimum (6, - \frac{1}{9})

Maximum (2, - 1), Minimum (6, - \frac{1}{9})

x + 5

3 x - 5

f (x) = x^{3} - 24 x^{2} + 144 x

f (x) = e^{(6 x - \frac{1}{6})} + 6

(- 4.4) (0.8)
