domain of y= 1/2 cos(x)-2

domain

y = \frac{1}{2} cos (x) - 2

- \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

lo g_{5} (x)

f (x) = \frac{x - 3}{2 x ^{2} + x - 21}

f (x) = \frac{x - 6}{x ^{2} + x - 42}

f (x) = \frac{2 x - 3}{x}

f (x) = \frac{7 x + 6}{x - 1}

What is the domain of y= 1/2 cos(x)-2 ?
The domain of y= 1/2 cos(x)-2 is -infinity <x<infinity
