domain of sqrt((3-x)(-7-x))

domain

(3 - x) (- 7 - x)

x \leq - 7 or x \geq 3

Interval Notation

(- \infty, - 7] \cup [3, \infty)

Solution steps

Find non-negative values for radicals:

x \leq - 7 or x \geq 3

The function domain

x \leq - 7 or x \geq 3

y = \frac{5}{3} x - 2

\frac{x ^{2}}{x ^{2} + 8}

(x^{2} + 4)^{2}

f (x) = \frac{5}{2} cos (\frac{x}{2})

(8, - 7), (9, 8)

What is the domain of sqrt((3-x)(-7-x)) ?
