extreme f(x)=19+4x-x^2

Solution

extreme points

f (x) = 19 + 4 x - x^{2}

Solution

Maximum (2, 23)

Solution steps

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

Find intervals:

Increasing

: - \infty < x < 2,

Decreasing

: 2 < x < \infty

Plug

x = 2

into

19 + 4 x - x^{2} : 23

Maximum (2, 23)

Popular Examples

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

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

extreme f(x)=e^x+e^{-x}extreme points

f (x) = e^{x} + e^{- x}

extreme 5x+9x^{-1}extreme points

5 x + 9 x^{- 1}

extreme f(x)=3x^3-3x^2+12x-5,-1<= x<= 1 extreme points

f (x) = 3 x^{3} - 3 x^{2} + 12 x - 5, - 1 \leq x \leq 1

extreme f(x,y)=ln(-x^2-y^2+4)extreme points

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