domain of f(x)=x^2-11

domain

f (x) = x^{2} - 11

- \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) = ln (2 x + 8)

f (x) = ln (2 x + 3)

f (x) = arcsin (e^{x})

f (x) = \frac{1}{x + 8}

f (x) = 8 - x^{2}

What is the domain of f(x)=x^2-11 ?
The domain of f(x)=x^2-11 is -infinity <x<infinity
