domain of f(x)=5x^2-4y^2-20=0

domain

f (x) = 5 x^{2} - 4 y^{2} - 20 = 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) = \frac{1 + x}{9 - x}

f (x) = e^{0.5 x} + 576 e^{- 0.5 x}

\frac{x - 5}{3} + 4

f (x) = \frac{- 7 x - 2}{4 x + 7}
