domain of f(x)=3-((13)/(x^2+5))

domain

f (x) = 3 - (\frac{13}{x ^{2} + 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

f (x) = \frac{8 - x}{x + 3}

\frac{1}{x ^{2}} - 1

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

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

f (x) = 81 x
