monotone f(x)=10x^3+9

monotone intervals

f (x) = 10 x^{3} + 9

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

Solution steps

f^{'} (x) = 30 x^{2}

Find intervals:

Increasing

: - \infty < x < 0,

Increasing

: 0 < x < \infty

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

x^{2} ln (x)

x^{2} - 2 x

f (x) = \frac{7}{x - 1}

y = (x - 2)^{2}

f (x) = - 3 x + 5
