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

domain

f (x) = 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{x}{ln ( x )}

\frac{4}{t ^{2} - 9}

f (x) = 5 x^{4} - 3

f (x) = - (x - 5)^{2} - 9

ln (x - 3)
