domain of f(x,y)=x^2-y^2+9=0

domain

f (x, y) = x^{2} - y^{2} + 9 = 0

- \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) = - 1 + lo g_{4} (x - 3)

- x - 1

f (x) = x^{6} - 3 x^{2}

\frac{tan ( x )}{7}

f (x) = e^{x - π} + 4
