extreme 2x^3-6x^2-210x+7

extreme points

2 x^{3} - 6 x^{2} - 210 x + 7

Maximum (- 5, 657), Minimum (7, - 1071)

Solution steps

f^{'} (x) = 6 x^{2} - 12 x - 210

Find intervals:

Increasing

: - \infty < x < - 5,

Decreasing

: - 5 < x < 7,

Increasing

: 7 < x < \infty

Plug

x = - 5

into

2 x^{3} - 6 x^{2} - 210 x + 7 : 657

Maximum (- 5, 657)

Plug

x = 7

into

2 x^{3} - 6 x^{2} - 210 x + 7 : - 1071

Minimum (7, - 1071)

Maximum (- 5, 657), Minimum (7, - 1071)

f (x, y) = 2 x^{2} - 8 y^{2} - 13

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

y = - x^{2} + 5, (- 2, 4)

f (x) = 4 sin (x) + 3 cos (x)

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