domain of f(x)=sqrt((x-3)(x+6))

domain

f (x) = (x - 3) (x + 6)

x \leq - 6 or x \geq 3

Interval Notation

(- \infty, - 6] \cup [3, \infty)

Solution steps

Find non-negative values for radicals:

x \leq - 6 or x \geq 3

The function domain

x \leq - 6 or x \geq 3

sec (x) - csc (x)

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

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

f (x) = 4 x

x^{2} - x - 30

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