extreme f(x)=-2+x-5x^2

Solution

extreme points

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

Solution

Maximum (\frac{1}{10}, - \frac{39}{20})

Solution steps

f^{'} (x) = - 10 x + 1

Find intervals:

Increasing

: - \infty < x < \frac{1}{10},

Decreasing

: \frac{1}{10} < x < \infty

Plug

x = \frac{1}{10}

into

- 2 + x - 5 x^{2} : - \frac{39}{20}

Maximum (\frac{1}{10}, - \frac{39}{20})

Popular Examples

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

f (x) = 4 sin (x) + 4 cos (x), 0 \leq x \leq 2 π

extreme f(x)=100x-(800+50x+2x^2)extreme points

f (x) = 100 x - (800 + 50 x + 2 x^{2})

extreme pi/(24)sec^2((pix)/(24))extreme points

\frac{π}{24} sec^{2} (\frac{π x}{24})

extreme f(x)=9x^{2/3}-x,0<= x<= 729 extreme points

f (x) = 9 x^{\frac{2}{3}} - x, 0 \leq x \leq 729

extreme f(x)=(x^2+4)/(4x),1<= x<= 10 extreme points

f (x) = \frac{x ^{2} + 4}{4 x}, 1 \leq x \leq 10
