domain of sqrt(x^2+x+6)

domain

x^{2} + x + 6

- \infty < x < \infty

Interval Notation

(- \infty, \infty)

Solution steps

Find non-negative values for radicals:

- \infty < x < \infty

The function has no undefined points nor domain constraints. Therefore, the domain is

- \infty < x < \infty

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

\frac{x ^{3} + 2 x ^{2} + x}{x ^{2} - x - 2}

y = \frac{tan ( x )}{sin ( x )} + \frac{c}{sin ( x )}

f (x) = - ∣ x ∣ + ∣ x - 1 ∣

f (x) = x - 4 + 1
