monotone 8/(xsqrt(x^2-4))

monotone intervals

\frac{8}{x x ^{2} - 4}

Decreasing : - \infty < x < - 2, Decreasing : 2 < x < \infty

Solution steps

f^{'} (x) = - \frac{8 ( 2 x ^{2} - 4 )}{x ^{2} ( x ^{2} - 4 ) x ^{2} - 4}

Find intervals:

Decreasing

: - \infty < x < - 2,

Decreasing

: 2 < x < \infty

Decreasing : - \infty < x < - 2, Decreasing : 2 < x < \infty

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

\frac{2 x + 11}{3 x + 19}

2 x - 3 y = \frac{7}{5}

f (x) = x^{2} + 7 x

f (x) = \frac{4}{11 - 2 x}
