extreme 1x^3-4x^2-3x+30

extreme

Maximum (- \frac{1}{3}, \frac{824}{27}), Minimum (3, 12)

Solution steps

f^{'} (x) = 3 x^{2} - 8 x - 3

Find intervals:

Increasing

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

Decreasing

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

Increasing

: 3 < x < \infty

Plug

x = - \frac{1}{3}

into

1 x^{3} - 4 x^{2} - 3 x + 30 : \frac{824}{27}

Maximum (- \frac{1}{3}, \frac{824}{27})

Plug

x = 3

into

1 x^{3} - 4 x^{2} - 3 x + 30 : 12

Minimum (3, 12)

Maximum (- \frac{1}{3}, \frac{824}{27}), Minimum (3, 12)
