domain of sqrt(x^2+5x+6)

domain

x^{2} + 5 x + 6

x \leq - 3 or x \geq - 2

Interval Notation

(- \infty, - 3] \cup [- 2, \infty)

Solution steps

Find non-negative values for radicals:

x \leq - 3 or x \geq - 2

The function domain

x \leq - 3 or x \geq - 2

4 x^{2} - 4 x + 21

(- 2, 3), (2, 1)

f (x) = x^{4} - 4 x^{3} + 1

f (x) = \frac{1}{64} x^{3}
