extreme f(x)= x/((x-7)^2)

Solution

extreme points

f (x) = \frac{x}{( x - 7 ) ^{2}}

Solution

Minimum (- 7, - \frac{1}{28})

Solution steps

f^{'} (x) = \frac{- 7 - x}{( x - 7 ) ^{3}}

Find intervals:

Decreasing

: - \infty < x < - 7,

Increasing

: - 7 < x < 7,

Decreasing

: 7 < x < \infty

Plug

x = - 7

into

\frac{x}{( x - 7 ) ^{2}} : - \frac{1}{28}

Minimum (- 7, - \frac{1}{28})

Popular Examples

extreme y=(e^x)/(x^2-3x+2)extreme points

y = \frac{e ^{x}}{x ^{2} - 3 x + 2}

extreme g(t)=t^4+t^3+t^2+1 extreme points

g (t) = t^{4} + t^{3} + t^{2} + 1

extreme f(x,y)=(x+y)^3-12xy extreme points

f (x, y) = (x + y)^{3} - 12 x y

extreme f(x_{1},x_{2})=x_{1}+x_{1}x_{2}+x_{2}extreme points

f (x_{1}, x_{2}) = x_{1} + x_{1} x_{2} + x_{2}

extreme f(x)=-x^2+2x+6 extreme points

f (x) = - x^{2} + 2 x + 6
