domain of 2cos(3x+pi)

domain

2 cos (3 x + π)

- \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

ln (4 - x)

f (x) = 3^{- 2 x + 8} - 1

- 5 x - 2

- 5 x + 5

\frac{x ^{3} + x}{1 - x ^{2}}
