The domain of the function f(x) is [tex]x \le 0[/tex]

How to determine the domain?

The equation of the function is given as:

[tex]f(x) = \sqrt{-2x[/tex]

The radicand must be at least 0.

So, we have:

[tex]-2x \ge 0[/tex]

Divide both sides by -2

[tex]x \le 0[/tex]

Hence, the domain of the function f(x) is [tex]x \le 0[/tex]
