extreme f(x)=14x+19x^{14/19}

extreme points

f (x) = 14 x + 19 x^{\frac{14}{19}}

Minimum (- 1, 5), Maximum (0, 0)

Solution steps

f^{'} (x) = 14 + \frac{14}{x ^{\frac{5}{19}}}

Find intervals:

Decreasing

: - \infty < x < - 1,

Increasing

: - 1 < x < \infty

Plug

x = - 1

into

14 x + 19 x^{\frac{14}{19}} : 5

Minimum (- 1, 5)

Plug

x = 0

into

14 x + 19 x^{\frac{14}{19}} : 0

Maximum (0, 0)

Minimum (- 1, 5), Maximum (0, 0)

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

f (x) = 3 cos (5 x) + sin (5 x)

f (x) = 11 x_{1} + 6 x_{1} x_{2} + 3 x_{2}

f (x) = 9 x^{4} - 26 x^{3} - 84 x^{2} + 72

f (x, y) = x^{3} + y^{2} - 3 x - 4 y
