extreme f(x)=3x^2+10x-5

Solution

extreme points

f (x) = 3 x^{2} + 10 x - 5

Solution

Minimum (- \frac{5}{3}, - \frac{40}{3})

Solution steps

f^{'} (x) = 6 x + 10

Find intervals:

Decreasing

: - \infty < x < - \frac{5}{3},

Increasing

: - \frac{5}{3} < x < \infty

Plug

x = - \frac{5}{3}

into

3 x^{2} + 10 x - 5 : - \frac{40}{3}

Minimum (- \frac{5}{3}, - \frac{40}{3})
