extreme f(x)=x^8e^x-6

extreme points

f (x) = x^{8} e^{x} - 6

Maximum (- 8, \frac{16777216}{e ^{8}} - 6), Minimum (0, - 6)

Solution steps

f^{'} (x) = e^{x} x^{8} + 8 e^{x} x^{7}

Find intervals:

Increasing

: - \infty < x < - 8,

Decreasing

: - 8 < x < 0,

Increasing

: 0 < x < \infty

Plug

x = - 8

into

x^{8} e^{x} - 6 : \frac{16777216}{e ^{8}} - 6

Maximum (- 8, \frac{16777216}{e ^{8}} - 6)

Plug

x = 0

into

x^{8} e^{x} - 6 : - 6

Minimum (0, - 6)

Maximum (- 8, \frac{16777216}{e ^{8}} - 6), Minimum (0, - 6)
