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

domain

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

g (x) = \frac{x + 4}{x ^{2} - 25}

x^{2} - x - 8

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

g (x) = - x + 8

x^{2} - x - 5
