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

domain

f (x) = ln (x^{2} + 4)

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

Find positive values for logs:

- \infty < x < \infty

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

f (x) = \frac{x + 1}{x}

\frac{x + 5}{1 - x - 2}

y = ln (x - 2)

1 - 4 x^{2}

y = \frac{1}{x ^{2} - 4}
