extreme f(x)=x^4-8x^3+10x^2+1

extreme

Minimum (0, 1), Maximum (1, 4), Minimum (5, - 124)

Solution steps

f^{'} (x) = 4 x^{3} - 24 x^{2} + 20 x

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < 1,

Decreasing

: 1 < x < 5,

Increasing

: 5 < x < \infty

Plug

x = 0

into

x^{4} - 8 x^{3} + 10 x^{2} + 1 : 1

Minimum (0, 1)

Plug

x = 1

into

x^{4} - 8 x^{3} + 10 x^{2} + 1 : 4

Maximum (1, 4)

Plug

x = 5

into

x^{4} - 8 x^{3} + 10 x^{2} + 1 : - 124

Minimum (5, - 124)

Minimum (0, 1), Maximum (1, 4), Minimum (5, - 124)
