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
