extreme f(x)=x^2+3x

Solution

extreme points

f (x) = x^{2} + 3 x

Solution

Minimum (- \frac{3}{2}, - \frac{9}{4})

Solution steps

f^{'} (x) = 2 x + 3

Find intervals:

Decreasing

: - \infty < x < - \frac{3}{2},

Increasing

: - \frac{3}{2} < x < \infty

Plug

x = - \frac{3}{2}

into

x^{2} + 3 x : - \frac{9}{4}

Minimum (- \frac{3}{2}, - \frac{9}{4})
