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

domain

f (x) = 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

f (x) = 1.1011 E 13

f (x) = \frac{4}{x + 2} + x

(6, 3), (- 1, - 5)

f (x) = 6 x^{2} - 6

x^{3} - 9 x^{2} + 15 x

What is the domain of f(x)=sqrt(x^2+5x+6) ?
The domain of f(x)=sqrt(x^2+5x+6) is x<=-3\lor x>=-2
