extreme f(x)=3x^{2/3}-2x[-1.1]

extreme points

f (x) = 3 x^{\frac{2}{3}} - 2 x [- 1.1]

Maximum (- \frac{1000}{1331}, 0.82644 \dots)

Solution steps

f^{'} (x) = \frac{2}{x ^{\frac{1}{3}}} + 2.2

Find intervals:

Decreasing

: - \infty < x < - \frac{10.648}{8},

Increasing

: - \frac{10.648}{8} < x < \infty

Plug

x = - \frac{1000}{1331}

into

3 x^{\frac{2}{3}} - 2 x [- 1.1] : 0.82644 \dots

Maximum (- \frac{1000}{1331}, 0.82644 \dots)

f (x) = x^{2} + 3 x + 5

f (x, y) = \frac{1}{3} 36 - 4 x^{2} - 9 y^{2}

f (x) = - x^{7} ln (3 x), (0, 4)

\frac{x ^{2}}{- x ^{2} + 4}

y = x^{x} I n (x^{5} + x)
