domain of f(x)=x^2+2xy+y^2+2x-2y-1=0

domain

f (x) = x^{2} + 2 x y + y^{2} + 2 x - 2 y - 1 = 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

\frac{2 x ^{2}}{x ^{2}} + \frac{7 x}{10 x} + \frac{15}{7}

f (x) = \frac{x + 5}{x}

f (x) = \frac{1}{7 - x}

f (x) = ln (- 4 + 4)

f (x) = 3 ∣ x ∣ - 4

What is the domain of f(x)=x^2+2xy+y^2+2x-2y-1=0 ?
The domain of f(x)=x^2+2xy+y^2+2x-2y-1=0 is -infinity <x<infinity
