extreme f(x)=x^2+5x+4

Solution

extreme points

f (x) = x^{2} + 5 x + 4

Solution

Minimum (- \frac{5}{2}, - \frac{9}{4})

Solution steps

f^{'} (x) = 2 x + 5

Find intervals:

Decreasing

: - \infty < x < - \frac{5}{2},

Increasing

: - \frac{5}{2} < x < \infty

Plug

x = - \frac{5}{2}

into

x^{2} + 5 x + 4 : - \frac{9}{4}

Minimum (- \frac{5}{2}, - \frac{9}{4})

Popular Examples

inverse of f(x)=(3-2x)/(3x+4)inverse

f (x) = \frac{3 - 2 x}{3 x + 4}

asymptotes of (-1)/(x-2)+4 asymptotes

\frac{- 1}{x - 2} + 4

asymptotes of (7x^2)/(8x^3)asymptotes

\frac{7 x ^{2}}{8 x ^{3}}

critical f(x)=36x^3-3x critical points

f (x) = 36 x^{3} - 3 x

parallel y= 1/2 x+9/4 ,(-5,2)parallel

y = \frac{1}{2} x + \frac{9}{4}, (- 5, 2)
