domain of f(x)=(-4sqrt(x))/(x^2+x)

domain

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

x > 0

Interval Notation

(0, \infty)

Solution steps

Find non-negative values for radicals:

x \geq 0

Find undefined (singularity) points:

x = 0, x = - 1

Combine real regions and undefined points for final function domain

x > 0

lo g_{5} (x + 3) - 2

y = - \frac{1}{x + 7}

\frac{7 x - 5}{- 5 x - 9}

f (x) = \frac{x}{x - 3} \cdot \frac{1}{x}

f (x) = \frac{9 \cdot x}{( 7 \cdot x - 1 )}
