domain of f(x)=3-x

domain

f (x) = 3 - x

- \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) = (12 - x)^{\frac{1}{4}}

f (x) = \frac{x}{1 - x ^{3}}

f (x) = - 3 - x + 2

2 x^{2} + 5 x - 3

f (x) = \frac{x + 3}{x - 9}
