domain of 2cos(x)

Solution

domain

2 cos (x)

Solution

- \infty < x < \infty

+1

Solution steps

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

- \infty < x < \infty

Popular Examples

domain of f(x)=x^{(2/3)}domain

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

intercepts of y=x^3-1 intercepts

y = x^{3} - 1

domain of f(x)= 1/(x-2)domain

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

asymptotes of f(x)=(3x^2+6x+9)/(x+9)asymptotes

f (x) = \frac{3 x ^{2} + 6 x + 9}{x + 9}

domain of sqrt(-7x+7)domain

- 7 x + 7
