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) = (x + 2)^{3}

f (x) = 10 x^{7}

f (x) = - 3 x - 9

f (x) = 9 + 5 x

y = \frac{x}{x ^{2} - 25}

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