extreme f(x)=4x^3-3x^2-6x+3

extreme points

f (x) = 4 x^{3} - 3 x^{2} - 6 x + 3

Maximum (- \frac{1}{2}, \frac{19}{4}), Minimum (1, - 2)

Solution steps

f^{'} (x) = 12 x^{2} - 6 x - 6

Find intervals:

Increasing

: - \infty < x < - \frac{1}{2},

Decreasing

: - \frac{1}{2} < x < 1,

Increasing

: 1 < x < \infty

Plug

x = - \frac{1}{2}

into

4 x^{3} - 3 x^{2} - 6 x + 3 : \frac{19}{4}

Maximum (- \frac{1}{2}, \frac{19}{4})

Plug

x = 1

into

4 x^{3} - 3 x^{2} - 6 x + 3 : - 2

Minimum (1, - 2)

Maximum (- \frac{1}{2}, \frac{19}{4}), Minimum (1, - 2)
