monotone (4-x)/(x-1)

monotone intervals

\frac{4 - x}{x - 1}

Decreasing : - \infty < x < 1, Decreasing : 1 < x < \infty

Solution steps

f^{'} (x) = - \frac{3}{( x - 1 ) ^{2}}

Find intervals:

Decreasing

: - \infty < x < 1,

Decreasing

: 1 < x < \infty

Decreasing : - \infty < x < 1, Decreasing : 1 < x < \infty

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

f (x) = \frac{( x + 4 )}{x ^{2}}

f (x) = 4 x^{3} - 12 x^{2} - 9 x + 27

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

6 x - 2
