domain of y=x^2+x+1

domain

y = 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

- 8 x + 6

f (x) = \frac{5}{x ^{2} - 4}

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

f (x) = 2 ln (1 + x^{2})

f (x) = \frac{x ^{2} - 9}{x ^{2} - 2 x - 3}
