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

Solution

extreme points

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

Solution

Minimum (- 1, 3)

Solution steps

f^{'} (x) = 4 x + 4

Find intervals:

Decreasing

: - \infty < x < - 1,

Increasing

: - 1 < x < \infty

Plug

x = - 1

into

2 x^{2} + 4 x + 5 : 3

Minimum (- 1, 3)

Popular Examples

extreme f(x)=9-x^2 extreme points

f (x) = 9 - x^{2}

extreme f(x)=(6x^2)/(x-6)extreme points

f (x) = \frac{6 x ^{2}}{x - 6}

extreme f(u,v)=(uv)/(u+v)extreme points

f (u, v) = \frac{uv}{u + v}

extreme f(x)=-x^2+9 extreme points

f (x) = - x^{2} + 9

extreme f(x)=x^3-3xy-y^3 extreme points

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