extreme 3x^2+2x[-2.1]

Solution

extreme points

3 x^{2} + 2 x [- 2.1]

Solution

Minimum (0.7, - 1.47)

Solution steps

f^{'} (x) = 6 x - 4.2

Find intervals:

Decreasing

: - \infty < x < 0.7,

Increasing

: 0.7 < x < \infty

Plug

x = 0.7

into

3 x^{2} + 2 x [- 2.1] : - 1.47

Minimum (0.7, - 1.47)

Popular Examples

extreme f(x)=x^3-48xy+64y^3 extreme points

f (x) = x^{3} - 48 x y + 64 y^{3}

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

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

extreme e^x(x-3)extreme points

e^{x} (x - 3)

extreme y=2sin(x)+9cos(x),0<= x<= 2pi extreme points

y = 2 sin (x) + 9 cos (x), 0 \leq x \leq 2 π

extreme f(x)=-10x^2+180x+10 extreme points

f (x) = - 10 x^{2} + 180 x + 10
