extreme f(x)=5-6x-4x^2

Solution

extreme points

f (x) = 5 - 6 x - 4 x^{2}

Solution

Maximum (- \frac{3}{4}, \frac{29}{4})

Solution steps

f^{'} (x) = - 8 x - 6

Find intervals:

Increasing

: - \infty < x < - \frac{3}{4},

Decreasing

: - \frac{3}{4} < x < \infty

Plug

x = - \frac{3}{4}

into

5 - 6 x - 4 x^{2} : \frac{29}{4}

Maximum (- \frac{3}{4}, \frac{29}{4})

Popular Examples

extreme f(x)=0.002x^3+9x+7626 extreme points

f (x) = 0.002 x^{3} + 9 x + 7626

extreme f(x,y)=sqrt((1-xy))extreme points

f (x, y) = (1 - x y)

extreme f(x)=x^3-15x^2+27x-8 extreme points

f (x) = x^{3} - 15 x^{2} + 27 x - 8

extreme f(x)=2x+37x^{2/37}extreme points

f (x) = 2 x + 37 x^{\frac{2}{37}}

extreme f(x,y)=11-7x+9y extreme points

f (x, y) = 11 - 7 x + 9 y
