domain of f(x)=(x^2)/(x^2+x+1)

domain

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

- \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{x ^{2} + 9 x + 18}{2 x ^{2} - 18}

f (x) = ln (9 t^{2} - 64)

f (x) = \frac{- 18 x - 21}{5 x + 6}

f (x) = 60 x + 4500

2 - x - lo g_{5} (12 - x^{2})
