extreme f(x)=(4860)/x+15x+717904

extreme points

f (x) = \frac{4860}{x} + 15 x + 717904

Maximum (- 18, 717364), Minimum (18, 718444)

Solution steps

f^{'} (x) = - \frac{4860}{x ^{2}} + 15

Find intervals:

Increasing

: - \infty < x < - 18,

Decreasing

: - 18 < x < 0,

Decreasing

: 0 < x < 18,

Increasing

: 18 < x < \infty

Plug

x = - 18

into

\frac{4860}{x} + 15 x + 717904 : 717364

Maximum (- 18, 717364)

Plug

x = 18

into

\frac{4860}{x} + 15 x + 717904 : 718444

Minimum (18, 718444)

Maximum (- 18, 717364), Minimum (18, 718444)

f (x, y) = - x^{3} + 4 x y - 2 y^{2} + 4 x + 1

f (x, y) = x^{3} + y^{3} + 9 x^{2} - 3 y^{2} + 15 x - 9 y

f (x) = 2 x + sin (4 x)

y = \frac{x ^{2} - 7}{x - 4}

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