monotone f(x)=x^2-4x-12

monotone intervals

f (x) = x^{2} - 4 x - 12

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

f (x) = \frac{4 x}{x ^{2} + 1}

- \frac{1}{2 - x + 9}

x^{2} + 4 x + 7

\frac{8}{x}

f (x) = \frac{- 4 x ^{2} - 2 x + 3}{2 x + 1}

What is the monotone f(x)=x^2-4x-12 ?
The monotone f(x)=x^2-4x-12 is Decreasing:-infinity <x<2,Increasing:2<x<infinity
