domain of f(x)=(4/10)^x

domain

f (x) = (\frac{4}{10})^{x}

- \infty < x < \infty

Solution steps

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

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

\frac{4 x - 11}{x - 9}

\frac{tan ( 2 x )}{x}

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

\frac{x ^{4}}{x ^{2} + x - 6}
