monotone f(x)=x^2+2x-8

monotone intervals

f (x) = x^{2} + 2 x - 8

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

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < - 1,

Increasing

: - 1 < x < \infty

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

(- 2, 1), (1, - 8)

f (x) = x^{2} - 4 x + 10

f (x) = \frac{x ^{2} - 81}{x - 9}

f (x) = tan (x \cdot 2) - x

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

What is the monotone f(x)=x^2+2x-8 ?
The monotone f(x)=x^2+2x-8 is Decreasing:-infinity <x<-1,Increasing:-1<x<infinity
