extreme 4xe^x

Solution

extreme points

4 x e^{x}

Solution

Minimum (- 1, - \frac{4}{e})

Solution steps

f^{'} (x) = 4 (e^{x} + e^{x} x)

Find intervals:

Decreasing

: - \infty < x < - 1,

Increasing

: - 1 < x < \infty

Plug

x = - 1

into

4 x e^{x} : - \frac{4}{e}

Minimum (- 1, - \frac{4}{e})

Popular Examples

extreme f(x)=(8+x)/(8-x),4<= x<= 6 extreme points

f (x) = \frac{8 + x}{8 - x}, 4 \leq x \leq 6

extreme f(x)=-1+4(1-x)^2 extreme points

f (x) = - 1 + 4 (1 - x)^{2}

extreme f(x)=2x^3-7x^2+4x extreme points

f (x) = 2 x^{3} - 7 x^{2} + 4 x

extreme x^4+2x^3+x^2+x+1 extreme points

x^{4} + 2 x^{3} + x^{2} + x + 1

extreme \sqrt[3]{10x^3+10}extreme points
