extreme f(x)=x^2+9x+2

Solution

extreme points

f (x) = x^{2} + 9 x + 2

Solution

Minimum (- \frac{9}{2}, - \frac{73}{4})

Solution steps

f^{'} (x) = 2 x + 9

Find intervals:

Decreasing

: - \infty < x < - \frac{9}{2},

Increasing

: - \frac{9}{2} < x < \infty

Plug

x = - \frac{9}{2}

into

x^{2} + 9 x + 2 : - \frac{73}{4}

Minimum (- \frac{9}{2}, - \frac{73}{4})

Popular Examples

inverse of f(x)=(2x-3)/3 inverse

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

domain of f(x)=(60)/(x(x+4))domain

f (x) = \frac{60}{x ( x + 4 )}

range of f(x)=6x^2+7x-24 range

f (x) = 6 x^{2} + 7 x - 24

inflection-(sin(x))/(cos(x))inflection points

- \frac{sin ( x )}{cos ( x )}

parity f(x)=x^2-x parity

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