extreme 7te^{-t/(15)}

Solution

extreme points

7 t e^{- \frac{t}{15}}

Solution

Maximum (15, \frac{105}{e})

Solution steps

f^{'} (t) = 7 (e^{- \frac{t}{15}} - \frac{e ^{- \frac{t}{15}} t}{15})

Find intervals:

Increasing

: - \infty < t < 15,

Decreasing

: 15 < t < \infty

Plug

t = 15

into

7 t e^{- \frac{t}{15}} : \frac{105}{e}

Maximum (15, \frac{105}{e})

extreme f(x)=(2x-2y-10)extreme points

f (x) = (2 x - 2 y - 10)

extreme f(x)=4x^2-24x+29 extreme points

f (x) = 4 x^{2} - 24 x + 29

extreme P(x,y)=2x+5y extreme points

P (x, y) = 2 x + 5 y

extreme f(x)=210+8x^3+x^4 extreme points

f (x) = 210 + 8 x^{3} + x^{4}
