domain of 5(1/2)^x-8

domain

5 (\frac{1}{2})^{x} - 8

- \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{7}{4 x ^{2} + 2}

\frac{x + 5}{x ^{2} - x - 30}

f (x) = \frac{x}{1 - 2 x}

y = \frac{x - 7}{x ^{2} - 12 x + 35}

f (x) = (\frac{2}{5})^{x}
