monotone f(x)=x^2+6x

monotone intervals

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

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

Solution steps

f^{'} (x) = 2 x + 6

Find intervals:

Decreasing

: - \infty < x < - 3,

Increasing

: - 3 < x < \infty

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

y (d) = \frac{1}{d + k e ^{d}}

f (x) = \frac{8 x ^{2} - 4 x + 11}{x + 5}

lo g_{3} (x)

f (x) = 1 - x^{3}
