extreme f(x)=x^4-12x^3+16x^2+5

extreme

Minimum (0, 5), Maximum (1, 10), Minimum (8, - 1019)

Solution steps

f^{'} (x) = 4 x^{3} - 36 x^{2} + 32 x

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < 1,

Decreasing

: 1 < x < 8,

Increasing

: 8 < x < \infty

Plug

x = 0

into

x^{4} - 12 x^{3} + 16 x^{2} + 5 : 5

Minimum (0, 5)

Plug

x = 1

into

x^{4} - 12 x^{3} + 16 x^{2} + 5 : 10

Maximum (1, 10)

Plug

x = 8

into

x^{4} - 12 x^{3} + 16 x^{2} + 5 : - 1019

Minimum (8, - 1019)

Minimum (0, 5), Maximum (1, 10), Minimum (8, - 1019)
