Which statement is true about the function f(x)= -√-x? a. the domain of the function is all negative real numbers b. the range of the function is all positive real numbers c. the domain and range of the function have opposite signs d. the domain and range of the function are the same

The correct answer is C) the domain and range of the function have opposite signs.

Explanation:

In order to calculate a square root of real numbers, we must use positive numbers.

Since we are taking the square root of negative x, this means x must be negative numbers; this will make each one the opposite of a negative, or a positive.

For the range, the output values of this function will be positive real numbers.

This means we use negatives for the domain and positives for the range, so they have opposite signs.
