extreme (x^3)/3+(x^2)/2-2x+7

extreme

Maximum (- 2, \frac{31}{3}), Minimum (1, \frac{35}{6})

Solution steps

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

Find intervals:

Increasing

: - \infty < x < - 2,

Decreasing

: - 2 < x < 1,

Increasing

: 1 < x < \infty

Plug

x = - 2

into

\frac{x ^{3}}{3} + \frac{x ^{2}}{2} - 2 x + 7 : \frac{31}{3}

Maximum (- 2, \frac{31}{3})

Plug

x = 1

into

\frac{x ^{3}}{3} + \frac{x ^{2}}{2} - 2 x + 7 : \frac{35}{6}

Minimum (1, \frac{35}{6})

Maximum (- 2, \frac{31}{3}), Minimum (1, \frac{35}{6})
