monotone f(x)=9x^2-x^3-3

monotone intervals

f (x) = 9 x^{2} - x^{3} - 3

Decreasing : - \infty < x < 0, Increasing : 0 < x < 6, Decreasing : 6 < x < \infty

Solution steps

f^{'} (x) = - 3 x^{2} + 18 x

Find intervals:

Decreasing

: - \infty < x < 0,

Increasing

: 0 < x < 6,

Decreasing

: 6 < x < \infty

Decreasing : - \infty < x < 0, Increasing : 0 < x < 6, Decreasing : 6 < x < \infty

f (x) = - x

y = \frac{1}{x + 5}

9 x - 7 y = - 7

x^{4} - 32 x^{3} + 290 x^{2} - 800 x + 6625

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