extreme f(x)=3x^2-5x-4

Solution

extreme points

f (x) = 3 x^{2} - 5 x - 4

Solution

Minimum (\frac{5}{6}, - \frac{73}{12})

Solution steps

f^{'} (x) = 6 x - 5

Find intervals:

Decreasing

: - \infty < x < \frac{5}{6},

Increasing

: \frac{5}{6} < x < \infty

Plug

x = \frac{5}{6}

into

3 x^{2} - 5 x - 4 : - \frac{73}{12}

Minimum (\frac{5}{6}, - \frac{73}{12})

Popular Examples

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

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

extreme f(x)=sqrt(x+1)extreme points

f (x) = x + 1

extreme f(x)=xe^{-5x^2}extreme points

f (x) = x e^{- 5 x^{2}}

extreme f(x)=x^3-12x^2+1 extreme points

f (x) = x^{3} - 12 x^{2} + 1

extreme f(x)=x^2+4x+6 extreme points

f (x) = x^{2} + 4 x + 6
