extreme y=-x^3+12x-16

extreme points

y = - x^{3} + 12 x - 16

Minimum (- 2, - 32), Maximum (2, 0)

Solution steps

f^{'} (x) = - 3 x^{2} + 12

Find intervals:

Decreasing

: - \infty < x < - 2,

Increasing

: - 2 < x < 2,

Decreasing

: 2 < x < \infty

Plug

x = - 2

into

- x^{3} + 12 x - 16 : - 32

Minimum (- 2, - 32)

Plug

x = 2

into

- x^{3} + 12 x - 16 : 0

Maximum (2, 0)

Minimum (- 2, - 32), Maximum (2, 0)

\frac{4}{7} sin (- \frac{2 π}{7} x)

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

9 x + 8

2 sin (2 x) + 3

f (x) = \frac{4 x ^{2} - 1}{6 x + 3}
