extreme f(x)=x^3-2x^2-15x+5(-2)

extreme

Maximum (- \frac{5}{3}, \frac{130}{27}), Minimum (3, - 46)

Solution steps

f^{'} (x) = 3 x^{2} - 4 x - 15

Find intervals:

Increasing

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

Decreasing

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

Increasing

: 3 < x < \infty

Plug

x = - \frac{5}{3}

into

x^{3} - 2 x^{2} - 15 x + 5 (- 2) : \frac{130}{27}

Maximum (- \frac{5}{3}, \frac{130}{27})

Plug

x = 3

into

x^{3} - 2 x^{2} - 15 x + 5 (- 2) : - 46

Minimum (3, - 46)

Maximum (- \frac{5}{3}, \frac{130}{27}), Minimum (3, - 46)
