monotone f(x)=3x^2+4x+1

monotone intervals

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

Decreasing : - \infty < x < - \frac{2}{3}, Increasing : - \frac{2}{3} < x < \infty

Solution steps

f^{'} (x) = 6 x + 4

Find intervals:

Decreasing

: - \infty < x < - \frac{2}{3},

Increasing

: - \frac{2}{3} < x < \infty

Decreasing : - \infty < x < - \frac{2}{3}, Increasing : - \frac{2}{3} < x < \infty

f (x) = - 3 x - 3

\frac{x + 2}{x ^{2} - 3 x - 10}

y = - 3 x^{2} + 9 x

f (x) = \frac{x + 4}{x - 7}
