domain of x^2+11

domain

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

y = \frac{1}{3 x + 1}

f (x) = \frac{1}{( - x + 4 )}

(3 k + 2) e^{- 3 k}

x^{2} - 9, x \geq 0

\frac{8 x - 9}{9 x + 5}
