domain of f(x)= 3/(2+x^2)

domain

f (x) = \frac{3}{2 + 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

f (x) = lo g_{10} (\frac{x + 1}{x - 3})

f (x) = \frac{x - 2}{x ^{2} - 9}

ln (2 x + 5)

f (x) = \frac{x - 1}{4 + x ∣ x ∣}

f (x) = (x^{3} - 1)^{\frac{2}{3}}

What is the domain of f(x)= 3/(2+x^2) ?
The domain of f(x)= 3/(2+x^2) is -infinity <x<infinity
