extreme f(x)=3x^2+12x-9

Solution

extreme points

f (x) = 3 x^{2} + 12 x - 9

Solution

Minimum (- 2, - 21)

Solution steps

f^{'} (x) = 6 x + 12

Find intervals:

Decreasing

: - \infty < x < - 2,

Increasing

: - 2 < x < \infty

Plug

x = - 2

into

3 x^{2} + 12 x - 9 : - 21

Minimum (- 2, - 21)

Popular Examples

extreme f(x)=395x^2-3160x^3 extreme points

f (x) = 395 x^{2} - 3160 x^{3}

extreme e^{x-1}extreme points

e^{x - 1}

extreme (8x^3)/3+15x^2-8x,-5<= x<= 1 extreme points

\frac{8 x ^{3}}{3} + 15 x^{2} - 8 x, - 5 \leq x \leq 1

extreme f(x)=2x^3-4x-1 extreme points

f (x) = 2 x^{3} - 4 x - 1

extreme y=0.25t^4-4.5t^2 extreme points

y = 0.25 t^{4} - 4.5 t^{2}
