domain of (x+1)/(x^2+4)

domain

\frac{x + 1}{x ^{2} + 4}

- \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

y = 3 + x

f (x) = \frac{x}{x - 18}

f (x) = lo g_{10} (\frac{3 x}{x + 5})

lo g_{2} (2 x + 4)

y = \frac{2}{x - 2}
