domain of 1/(4+x^2)

domain

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

- \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

h (x) = \frac{1}{x - 5}

f (x) = x^{5} + 1

f (x) = 96 x^{2} + 72 x + 11

f (x) = \frac{x - 4}{x ^{2} - 10}

y = \frac{3 a x ^{2}}{( 1 + x ^{3} )}
