domain of f(x)=x^2+y^2=4

domain

f (x) = x^{2} + y^{2} = 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

11 x + 6 y = 3

f (x) = x^{2} + 9 x

- \frac{1 - cos ( 4 x )}{1 + cos ( 4 x )}

h (t) = - 4.9 (t + 3)^{2} + 45.8

f (x) = \frac{6 x - 1}{2 x + 2}

What is the domain of f(x)=x^2+y^2=4 ?
The domain of f(x)=x^2+y^2=4 is -infinity <x<infinity
