domain of f(x)=1-2^x

domain

f (x) = 1 - 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

f (x) = 2 x^{3} + 15 x^{2} + 7

f (x) = 5 sin (\frac{π}{3} x + π) - 3

f (x) = 3 x + 4

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

∣ x - 2 ∣ + 3
