extreme 30x-28ln(x)

Solution

extreme points

30 x - 28 ln (x)

Solution

Minimum (\frac{14}{15}, 28 - 28 ln (\frac{14}{15}))

Solution steps

f^{'} (x) = 30 - \frac{28}{x}

Find intervals:

Decreasing

: 0 < x < \frac{14}{15},

Increasing

: \frac{14}{15} < x < \infty

Plug

x = \frac{14}{15}

into

30 x - 28 ln (x) : 28 - 28 ln (\frac{14}{15})

Minimum (\frac{14}{15}, 28 - 28 ln (\frac{14}{15}))

Popular Examples

extreme f(x,y)=9-x^2-y^2 extreme points

f (x, y) = 9 - x^{2} - y^{2}

extreme f(x)=e^{x^2-9x-1}extreme points

f (x) = e^{x^{2} - 9 x - 1}

extreme f(x,y)=5+2xy+(20)/x+(25)/y extreme points

f (x, y) = 5 + 2 x y + \frac{20}{x} + \frac{25}{y}

extreme f(x,y)=4xy-x^4-2y^2+2 extreme points

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

extreme f(x)=xsqrt(32-x^2)extreme points

f (x) = x 32 - x^{2}
