domain of 1/2-1/2 cos(2x-pi/4)

domain

\frac{1}{2} - \frac{1}{2} cos (2 x - \frac{π}{4})

- \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

\frac{15 x - 15}{x ^{2} + 3 x - 4}

ln (\frac{x + 1}{x - 2})

f (x) = x^{4} + 4 x^{3} + 1

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

\frac{∣ x ∣}{x + 1}
