domain of 2^x-1

domain

2^{x} - 1

- \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{3 x ^{2} + 5 x - 6}{x ^{2} - 9}

y = tan (3 x)

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

f (x) = x^{2} ln (4 + 6 x)

f (x) = ∣ x ∣ + 2 x - 3
