domain of (x^2-3)/(x^2+1)

domain

\frac{x ^{2} - 3}{x ^{2} + 1}

- \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 = lo g_{10} (2 x)

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

f (x) = 3 x^{2} + 1

2 - \frac{x}{2}

f (x) = 2 arcsin (\frac{x}{2} - 1) + π
