extreme f(x)= 1/3 x^3-4x^2+12x-5

extreme points

f (x) = \frac{1}{3} x^{3} - 4 x^{2} + 12 x - 5

Maximum (2, \frac{17}{3}), Minimum (6, - 5)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < 2,

Decreasing

: 2 < x < 6,

Increasing

: 6 < x < \infty

Plug

x = 2

into

\frac{1}{3} x^{3} - 4 x^{2} + 12 x - 5 : \frac{17}{3}

Maximum (2, \frac{17}{3})

Plug

x = 6

into

\frac{1}{3} x^{3} - 4 x^{2} + 12 x - 5 : - 5

Minimum (6, - 5)

Maximum (2, \frac{17}{3}), Minimum (6, - 5)

\frac{x ^{2} - 1}{x ^{2} + 1}

f (x) = x 2 - x

f (x) = 3 - (x + 1)^{3}

f (x, y, z) = x + y 2 + x 3

f (x) = \frac{x ^{2} + x - 38}{x ^{2} - 25}
