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

Solution

extreme points

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

Solution

Minimum (\frac{3}{2}, - \frac{25}{4})

Solution steps

f^{'} (x) = 2 x - 3

Find intervals:

Decreasing

: - \infty < x < \frac{3}{2},

Increasing

: \frac{3}{2} < x < \infty

Plug

x = \frac{3}{2}

into

x^{2} - 3 x - 4 : - \frac{25}{4}

Minimum (\frac{3}{2}, - \frac{25}{4})

Popular Examples

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

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

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

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

extreme f(x,y)= y/(x+y^3)extreme points

f (x, y) = \frac{y}{x + y ^{3}}

extreme f(x,y)=x^3+12xy^2-15x-24x extreme points

f (x, y) = x^{3} + 12 x y^{2} - 15 x - 24 x

extreme f(x)=sin(x)-cos^2(x),0<= x<= 2pi extreme points

f (x) = sin (x) - cos^{2} (x), 0 \leq x \leq 2 π
