extreme x^5-15x^3+3

extreme points

x^{5} - 15 x^{3} + 3

Maximum (- 3, 165), Saddle (0, 3), Minimum (3, - 159)

Solution steps

f^{'} (x) = 5 x^{4} - 45 x^{2}

Find intervals:

Increasing

: - \infty < x < - 3,

Decreasing

: - 3 < x < 0,

Decreasing

: 0 < x < 3,

Increasing

: 3 < x < \infty

Plug

x = - 3

into

x^{5} - 15 x^{3} + 3 : 165

Maximum (- 3, 165)

Plug

x = 0

into

x^{5} - 15 x^{3} + 3 : 3

Saddle (0, 3)

Plug

x = 3

into

x^{5} - 15 x^{3} + 3 : - 159

Minimum (3, - 159)

Maximum (- 3, 165), Saddle (0, 3), Minimum (3, - 159)

h (x) = \frac{θ x ^{4} + 3 θ x ^{3} + 3 θ x ^{2} + θ x}{x ^{3} + 2 x ^{2} + x}

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

f (x) = (16 - 2 x) (12 - 2 x) x

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

V (A, t) = A^{t}
