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

domain

\frac{3 x}{5 + 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

y = x^{2} - 1

2 arccsc (4 x - 3)

81 x

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