monotone x^2+2x-3

monotone intervals

x^{2} + 2 x - 3

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

f (x) = - 6

2 y = x

(5, - 3), (2, - 5)

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

(- 3, 1), (2, - 4)
