extreme 250+8x^3+x^4

Solution

extreme points

250 + 8 x^{3} + x^{4}

Solution

Minimum (- 6, - 182), Saddle (0, 250)

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < - 6,

Increasing

: - 6 < x < 0,

Increasing

: 0 < x < \infty

Plug

x = - 6

into

250 + 8 x^{3} + x^{4} : - 182

Minimum (- 6, - 182)

Plug

x = 0

into

250 + 8 x^{3} + x^{4} : 250

Saddle (0, 250)

Minimum (- 6, - 182), Saddle (0, 250)
