extreme f(x)=2x^2+14x-25

Solution

extreme points

f (x) = 2 x^{2} + 14 x - 25

Solution

Minimum (- \frac{7}{2}, - \frac{99}{2})

Solution steps

f^{'} (x) = 4 x + 14

Find intervals:

Decreasing

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

Increasing

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

Plug

x = - \frac{7}{2}

into

2 x^{2} + 14 x - 25 : - \frac{99}{2}

Minimum (- \frac{7}{2}, - \frac{99}{2})
