domain of sqrt(x^2-3)

domain

x^{2} - 3

x \leq - 3 or x \geq 3

Interval Notation

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

Solution steps

Find non-negative values for radicals:

x \leq - 3 or x \geq 3

The function domain

x \leq - 3 or x \geq 3

9 - 4 x^{2}

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

f (x) = - \frac{1}{2} (x - \frac{1}{3})^{2} - \frac{3}{2}

(x - 2)^{3}

f (x) = 5 sin (2 x)

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