domain of f(x)=2+ncos(x)

domain

f (x) = 2 + n cos (x)

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

f (x) = (\frac{7 x}{x - 5})

f (x) = \frac{x ^{2} - 4}{2 + x - 1}

f (x) = \frac{x ^{2} + 2 x - 3}{x ^{2} + 5 x + 6}

f (x) = \frac{3}{x - 3}
