extreme f(x)=(5-x)^{2/3}(1+x)^{1/3}

extreme points

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

Maximum (1, 2 \cdot 2^{\frac{2}{3}}), Minimum (5, 0)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - 1,

Increasing

: - 1 < x < 1,

Decreasing

: 1 < x < 5,

Increasing

: 5 < x < \infty

Plug

x = 1

into

(5 - x)^{\frac{2}{3}} (1 + x)^{\frac{1}{3}} : 2 \cdot 2^{\frac{2}{3}}

Maximum (1, 2 \cdot 2^{\frac{2}{3}})

Plug

x = 5

into

(5 - x)^{\frac{2}{3}} (1 + x)^{\frac{1}{3}} : 0

Minimum (5, 0)

Maximum (1, 2 \cdot 2^{\frac{2}{3}}), Minimum (5, 0)

x^{\frac{1}{3}} (x^{2} - 9)

f (x) = x \cdot e^{x}

f (x) = x^{3} + 2 x^{2} - 20 x, 0 \leq x \leq 3

x^{\frac{13}{3}} - 9 x^{\frac{7}{3}}

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