extreme f(x)=8-3x-6x^2

Solution

extreme points

f (x) = 8 - 3 x - 6 x^{2}

Solution

Maximum (- \frac{1}{4}, \frac{67}{8})

Solution steps

f^{'} (x) = - 12 x - 3

Find intervals:

Increasing

: - \infty < x < - \frac{1}{4},

Decreasing

: - \frac{1}{4} < x < \infty

Plug

x = - \frac{1}{4}

into

8 - 3 x - 6 x^{2} : \frac{67}{8}

Maximum (- \frac{1}{4}, \frac{67}{8})

Popular Examples

extreme f(x)=4cos^2(x),0<= x<= pi extreme points

f (x) = 4 cos^{2} (x), 0 \leq x \leq π

extreme cos(t)extreme points

cos (t)

extreme f(x)=x^4-32x^2+8 extreme points

f (x) = x^{4} - 32 x^{2} + 8

extreme f(x,y)=2x^3-5xy^2+4y^3 extreme points

f (x, y) = 2 x^{3} - 5 x y^{2} + 4 y^{3}

extreme f(x,y)=2x^2-xy+y^2-6x-9y+7 extreme points

f (x, y) = 2 x^{2} - x y + y^{2} - 6 x - 9 y + 7
