domain of f(x)=4-2x

domain

f (x) = 4 - 2 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

(3.13) (20.3)

x^{2} + 3 x + 14

f (x) = \frac{x - 3}{3 x - 6}

f (x) = x + 4 g (x) = x - 4

x + 3
