monotone f(x)=3x^2-6x

monotone intervals

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

Decreasing : - \infty < x < 1, Increasing : 1 < x < \infty

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 1,

Increasing

: 1 < x < \infty

Decreasing : - \infty < x < 1, Increasing : 1 < x < \infty

f (x) = \frac{4}{x + 9}

f (x) = \frac{x - 6}{x + 1}

∣ x ∣

f (x) = 3 x - 6

f (x) = \frac{1}{2} x + 8
