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

domain

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

(x - 1) (x - 2) (x - 3) (x - 4)

10 - \frac{1}{5 x}

f (x) = 4 x^{\frac{1}{3}} - x^{\frac{4}{3}}

g (x) = 2^{x} - 4

\frac{x ^{2} - 3 x - 4}{2 x ^{2} + 4 x}
