extreme f(x)=(3x^2)/(x^2-9)

Solution

extreme points

f (x) = \frac{3 x ^{2}}{x ^{2} - 9}

Solution

Maximum (0, 0)

Solution steps

f^{'} (x) = - \frac{54 x}{( x ^{2} - 9 ) ^{2}}

Find intervals:

Increasing

: - \infty < x < - 3,

Increasing

: - 3 < x < 0,

Decreasing

: 0 < x < 3,

Decreasing

: 3 < x < \infty

Plug

x = 0

into

\frac{3 x ^{2}}{x ^{2} - 9} : 0

Maximum (0, 0)

extreme f(x)=64-x^2 extreme points

f (x) = 64 - x^{2}

extreme f(x)=x+7^{2/3}extreme points

f (x) = x + 7^{\frac{2}{3}}

extreme f(x)=-2x^4+4y^4+16x^2-32y^2+1/18 extreme points

f (x) = - 2 x^{4} + 4 y^{4} + 16 x^{2} - 32 y^{2} + \frac{1}{18}

extreme 20(t/(12)-ln(t/(12)))+30 extreme points
