extreme f(x)=x^2+7x-3

Solution

extreme points

f (x) = x^{2} + 7 x - 3

Solution

Minimum (- \frac{7}{2}, - \frac{61}{4})

Solution steps

f^{'} (x) = 2 x + 7

Find intervals:

Decreasing

: - \infty < x < - \frac{7}{2},

Increasing

: - \frac{7}{2} < x < \infty

Plug

x = - \frac{7}{2}

into

x^{2} + 7 x - 3 : - \frac{61}{4}

Minimum (- \frac{7}{2}, - \frac{61}{4})
