domain of (x^2+2)/3

domain

\frac{x ^{2} + 2}{3}

- \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) = \frac{x ^{2}}{4 - x}

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

f (x) = - 2 (x - 4)^{2} + 1

2 x^{2} + 3 x + 4

- 35 - 18 x
