domain of 2^x-4

domain

2^{x} - 4

- \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

- 2 x - 3 + 6

f (x) = x^{2} + 12 x + 1

f (x) = \frac{x - 7}{x ^{2} + 36}

5 x - 12

\frac{x ^{2} - 1}{4 x - 5}
