extreme f(x)= 1/4 x^4-3/2 x^2

extreme points

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

Minimum (- 3, - \frac{9}{4}), Maximum (0, 0), Minimum (3, - \frac{9}{4})

Solution steps

f^{'} (x) = x^{3} - 3 x

Find intervals:

Decreasing

: - \infty < x < - 3,

Increasing

: - 3 < x < 0,

Decreasing

: 0 < x < 3,

Increasing

: 3 < x < \infty

Plug

x = - 3

into

\frac{1}{4} x^{4} - \frac{3}{2} x^{2} : - \frac{9}{4}

Minimum (- 3, - \frac{9}{4})

Plug

x = 0

into

\frac{1}{4} x^{4} - \frac{3}{2} x^{2} : 0

Maximum (0, 0)

Plug

x = 3

into

\frac{1}{4} x^{4} - \frac{3}{2} x^{2} : - \frac{9}{4}

Minimum (3, - \frac{9}{4})

Minimum (- 3, - \frac{9}{4}), Maximum (0, 0), Minimum (3, - \frac{9}{4})

f (x) = x^{4} + 4 x^{3} + 5

f (x, y) = 5 x + 2 y

f (x) = 5 x^{7} - 7 x^{5} - 7

\frac{x ^{2} + 4}{x ^{2} - 25}

f (x) = - 3 x^{3} + 6 x^{2}
