domain of f(x)=x^2+y^2=9

domain

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

- \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

f (x) = 2 π r^{2} + 8 π r

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

f (x) = \frac{4 x + 3}{x ^{2} - 1}

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

f (x) = 4 (2^{- 2 x + 7}) - 5

What is the domain of f(x)=x^2+y^2=9 ?
The domain of f(x)=x^2+y^2=9 is -infinity <x<infinity
