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

extreme

Maximum (- \frac{5}{3}, \frac{175}{27}), Minimum (1, - 3)

Solution steps

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

Find intervals:

Increasing

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

Decreasing

: - \frac{5}{3} < x < 1,

Increasing

: 1 < x < \infty

Plug

x = - \frac{5}{3}

into

x^{3} + x^{2} - 5 x : \frac{175}{27}

Maximum (- \frac{5}{3}, \frac{175}{27})

Plug

x = 1

into

x^{3} + x^{2} - 5 x : - 3

Minimum (1, - 3)

Maximum (- \frac{5}{3}, \frac{175}{27}), Minimum (1, - 3)
