monotone f(x)=x^2-4x-5

monotone intervals

f (x) = x^{2} - 4 x - 5

Decreasing : - \infty < x < 2, Increasing : 2 < x < \infty

Solution steps

f^{'} (x) = 2 x - 4

Find intervals:

Decreasing

: - \infty < x < 2,

Increasing

: 2 < x < \infty

Decreasing : - \infty < x < 2, Increasing : 2 < x < \infty

(3.8) (9.28)

f (x) = - 4 x + 1

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

y + 8 x = 4 (3.4)

\frac{2 x - 3}{x + 4}
