domain of f(x)=5*x^2+81

domain

f (x) = 5 \cdot x^{2} + 81

- \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

ln (- 2 - y^{2})

x^{3} + x

\frac{x}{x - 1 - 3}

g (x) = x^{3}

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