monotone f(x)=21x^2-x^3

monotone intervals

f (x) = 21 x^{2} - x^{3}

Decreasing : - \infty < x < 0, Increasing : 0 < x < 14, Decreasing : 14 < x < \infty

Solution steps

f^{'} (x) = 42 x - 3 x^{2}

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < 14,

Decreasing

: 14 < x < \infty

Decreasing : - \infty < x < 0, Increasing : 0 < x < 14, Decreasing : 14 < x < \infty

(22.42) (1.22)

x^{4} - 12 x^{3} + 48 x^{2} - 64 x

\frac{1}{ln ( x )}

f (x) = \frac{1}{2} x^{3} - 2

y = - 6 (x - 4)^{2} - 1
