extreme f(x)=3x^2+15x+18

Solution

extreme

Solution

Minimum (- \frac{5}{2}, - \frac{3}{4})

Solution steps

f^{'} (x) = 6 x + 15

Find intervals:

Decreasing

: - \infty < x < - \frac{5}{2},

Increasing

: - \frac{5}{2} < x < \infty

Plug

x = - \frac{5}{2}

into

3 x^{2} + 15 x + 18 : - \frac{3}{4}

Minimum (- \frac{5}{2}, - \frac{3}{4})
