extreme f(x)=-x^2-5x-2

Solution

extreme points

f (x) = - x^{2} - 5 x - 2

Solution

Maximum (- \frac{5}{2}, \frac{17}{4})

Solution steps

f^{'} (x) = - 2 x - 5

Find intervals:

Increasing

: - \infty < x < - \frac{5}{2},

Decreasing

: - \frac{5}{2} < x < \infty

Plug

x = - \frac{5}{2}

into

- x^{2} - 5 x - 2 : \frac{17}{4}

Maximum (- \frac{5}{2}, \frac{17}{4})

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

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

extreme F(X,Y)=1-X^2+2Y^2 extreme points

F (X, Y) = 1 - X^{2} + 2 Y^{2}

extreme f(x)=8+12x^2-8x^3 extreme points

f (x) = 8 + 12 x^{2} - 8 x^{3}

extreme f(x)=x^3-15x^2+78x+5 extreme points

f (x) = x^{3} - 15 x^{2} + 78 x + 5

extreme x^2-2xy+2y^2-2x+4y-1 extreme points

x^{2} - 2 x y + 2 y^{2} - 2 x + 4 y - 1
