extreme f(x)=ln(7+x^2)

Solution

extreme points

f (x) = ln (7 + x^{2})

Solution

Minimum (0, ln (7))

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < \infty

Plug

x = 0

into

ln (7 + x^{2}) : ln (7)

Minimum (0, ln (7))

Popular Examples

extreme y=-x^3+3/2 x^2+18x extreme points

y = - x^{3} + \frac{3}{2} x^{2} + 18 x

extreme 3x+3 extreme points

3 x + 3

extreme (x-2)^3+1 extreme points

(x - 2)^{3} + 1

extreme (5x)/(x^2+9)extreme points

\frac{5 x}{x ^{2} + 9}

extreme f(x)=(1+x/5)x^{2/3}extreme points

f (x) = (1 + \frac{x}{5}) x^{\frac{2}{3}}
