extreme f(x)=2x^3-11/2 x^2-10x+2

extreme points

f (x) = 2 x^{3} - \frac{11}{2} x^{2} - 10 x + 2

Maximum (- \frac{2}{3}, \frac{152}{27}), Minimum (\frac{5}{2}, - \frac{209}{8})

Solution steps

f^{'} (x) = 6 x^{2} - 11 x - 10

Find intervals:

Increasing

: - \infty < x < - \frac{2}{3},

Decreasing

: - \frac{2}{3} < x < \frac{5}{2},

Increasing

: \frac{5}{2} < x < \infty

Plug

x = - \frac{2}{3}

into

2 x^{3} - \frac{11}{2} x^{2} - 10 x + 2 : \frac{152}{27}

Maximum (- \frac{2}{3}, \frac{152}{27})

Plug

x = \frac{5}{2}

into

2 x^{3} - \frac{11}{2} x^{2} - 10 x + 2 : - \frac{209}{8}

Minimum (\frac{5}{2}, - \frac{209}{8})

Maximum (- \frac{2}{3}, \frac{152}{27}), Minimum (\frac{5}{2}, - \frac{209}{8})
