domain of sqrt(4x^2-32)

domain

4 x^{2} - 32

x \leq - 22 or x \geq 22

Interval Notation

(- \infty, - 22] \cup [22, \infty)

Solution steps

Find non-negative values for radicals:

x \leq - 22 or x \geq 22

The function domain

x \leq - 22 or x \geq 22

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

(1, 9), (5, - 3)

x - y = 3

f (x) = 2 cos (2 π x)

\frac{1}{4 ( \frac{( 1 - x )}{x} ) + 1}

What is the domain of sqrt(4x^2-32) ?
The domain of sqrt(4x^2-32) is x<=-2sqrt(2)\lor x>= 2sqrt(2)
