extreme-5x^2+8x

Solution

extreme points

- 5 x^{2} + 8 x

Solution

Maximum (\frac{4}{5}, \frac{16}{5})

Solution steps

f^{'} (x) = - 10 x + 8

Find intervals:

Increasing

: - \infty < x < \frac{4}{5},

Decreasing

: \frac{4}{5} < x < \infty

Plug

x = \frac{4}{5}

into

- 5 x^{2} + 8 x : \frac{16}{5}

Maximum (\frac{4}{5}, \frac{16}{5})

Popular Examples

extreme f(x)=x^4-5x^{3/2}extreme points

f (x) = x^{4} - 5 x^{\frac{3}{2}}

extreme f(x)=-2x^3+45x^2-300x,4<= x<= 11 extreme points

f (x) = - 2 x^{3} + 45 x^{2} - 300 x, 4 \leq x \leq 11

extreme f(x,y)=(-20)/9 x^3-5x^2y+45y extreme points

f (x, y) = \frac{- 20}{9} x^{3} - 5 x^{2} y + 45 y

extreme f(x)=(6-x)/2 extreme points

f (x) = \frac{6 - x}{2}

extreme x^2-2x-1 extreme points

x^{2} - 2 x - 1
