monotone 2x^2-12x+20

monotone intervals

2 x^{2} - 12 x + 20

Decreasing : - \infty < x < 3, Increasing : 3 < x < \infty

Solution steps

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

Find intervals:

Decreasing

: - \infty < x < 3,

Increasing

: 3 < x < \infty

Decreasing : - \infty < x < 3, Increasing : 3 < x < \infty

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

f (x) = 3 + \frac{x ^{2} - 10}{x - 2}

y = x^{2} + 2 x + 18

f (x) = x^{2} - 6 x + 8

\frac{2 x}{x ^{2} + 2 x}
