domain of f(x)=3+cos(2t)

domain

f (x) = 3 + cos (2 t)

- \infty < t < \infty

Interval Notation

(- \infty, \infty)

Solution steps

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

- \infty < t < \infty

\frac{sin ( x )}{x ^{2}}

+ x^{2} - 7

x e^{- 2 x}

x^{3} - 6 x^{2} + 8 x

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

What is the domain of f(x)=3+cos(2t) ?
The domain of f(x)=3+cos(2t) is -infinity <t<infinity
