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

Solution

extreme

Solution

Minimum (- \frac{1}{2}, \frac{15}{4})

Solution steps

f^{'} (x) = 2 x + 1

Find intervals:

Decreasing

: - \infty < x < - \frac{1}{2},

Increasing

: - \frac{1}{2} < x < \infty

Plug

x = - \frac{1}{2}

into

x^{2} + x + 4 : \frac{15}{4}

Minimum (- \frac{1}{2}, \frac{15}{4})
