Answer 1

(a) The domain of the function is all negative real number

Explanation:

Given

`f(x) = -\sqrt{-x`

Required

Determine the domain

The domain is the possible values of x which f(x) will be defined.

So, for f(x) to be true:, the following condition must be met:

`-x > 0`

Divide both sides by -1

`x < 0`

Hence, (a) is true
