domain of f(x)= x/(x^2+3x+5)

domain

f (x) = \frac{x}{x ^{2} + 3 x + 5}

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

+ X^{3}

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

f (x) = \frac{3 x}{( x - 2 ) ( x + 4 )}

\frac{3 x + 1}{4}

- 4 x + 4
