monotone f(x)=8-x^2

monotone intervals

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

Increasing : - \infty < x < 0, Decreasing : 0 < x < \infty

Solution steps

f^{'} (x) = - 2 x

Find intervals:

Increasing

: - \infty < x < 0,

Decreasing

: 0 < x < \infty

Increasing : - \infty < x < 0, Decreasing : 0 < x < \infty

\frac{4}{\frac{4}{x}}

f (x) = - 7 cos (4 x)

f (x) = x e^{x}

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

f (x) = - 1.8
