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

Solution

extreme points

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

Solution

Minimum (- \frac{1}{10}, - \frac{81}{20})

Solution steps

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

Find intervals:

Decreasing

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

Increasing

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

Plug

x = - \frac{1}{10}

into

5 x^{2} + x - 4 : - \frac{81}{20}

Minimum (- \frac{1}{10}, - \frac{81}{20})

Popular Examples

inverse of f(x)=-sqrt(x+1)inverse

f (x) = - x + 1

inverse of f(x)=-1/9 x+9 inverse

f (x) = - \frac{1}{9} x + 9

inverse of 4-x^2 inverse

4 - x^{2}

inverse of f(x)=(3+x)/x inverse

f (x) = \frac{3 + x}{x}

range of f(x)=-2x+3 range

f (x) = - 2 x + 3
