monotone f(x)=x^2-2x-3

monotone intervals

f (x) = 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

(x - 7)^{2} + 8

6 x - 2

m = 7, (- 3, 4)

f (x) = 2 (x + 1)^{2}

f (x) = \frac{3 x}{( 7 x + 14 )}
