domain of (2x)^{1/3}-7

domain

(2 x)^{\frac{1}{3}} - 7

- \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 + 4}{x - 7}

\frac{2 x ^{2} + 6 x + 5}{x ^{2} + 3 x + 2}

f (x) = 2 x + 4

y = arcsin (x) + π

f (x) = (x) = x
