extreme f(x)=7x-x^2

Solution

extreme points

f (x) = 7 x - x^{2}

Solution

Maximum (\frac{7}{2}, \frac{49}{4})

Solution steps

f^{'} (x) = 7 - 2 x

Find intervals:

Increasing

: - \infty < x < \frac{7}{2},

Decreasing

: \frac{7}{2} < x < \infty

Plug

x = \frac{7}{2}

into

7 x - x^{2} : \frac{49}{4}

Maximum (\frac{7}{2}, \frac{49}{4})

Popular Examples

extreme f(x)=ln(4-ln(x))extreme points

f (x) = ln (4 - ln (x))

extreme f(x)=x^2-y^2x-xy extreme points

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

extreme f(x)=-x^3+6x^2+63x extreme points

f (x) = - x^{3} + 6 x^{2} + 63 x

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

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

extreme f(x)=5x^2+10x extreme points

f (x) = 5 x^{2} + 10 x
