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

Solution

extreme points

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

Solution

Maximum (0, - 4)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < \infty

Plug

x = 0

into

- 2 x^{2} - 4 : - 4

Maximum (0, - 4)

Popular Examples

extreme y=xsqrt(4-x)extreme points

y = x 4 - x

extreme f(x)=(3x+1)^5(2x+3)^2(2-x)^3 extreme points

f (x) = (3 x + 1)^{5} (2 x + 3)^{2} (2 - x)^{3}

extreme y=2x^3-12x^2-270x+2 extreme points

y = 2 x^{3} - 12 x^{2} - 270 x + 2

extreme y=0.0004x^2-0.0118x+2.6821 extreme points

y = 0.0004 x^{2} - 0.0118 x + 2.6821

extreme sqrt(x)(8/5 x^3-2x^2)extreme points

x (\frac{8}{5} x^{3} - 2 x^{2})
