domain of f(x)=12-2x

domain

f (x) = 12 - 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

\frac{5 x - 5}{2 x + 3}

f (x) = 2 x - 3, - 2 \leq x < 1

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

(\frac{1}{2})^{x} - 1

f (x) = \frac{e ^{x}}{x ^{2} - 1}
