extreme f(x)=x^2+9x-5

Solution

extreme

Solution

Minimum (- \frac{9}{2}, - \frac{101}{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 - 5 : - \frac{101}{4}

Minimum (- \frac{9}{2}, - \frac{101}{4})
