Which of the following functions has a domain of x ≥ 0?
linear
squaring
square root
cubing

C. Square root.

Step-by-step explanation:

We have been given 4 choices. We are asked to determine, which of the given functions has a domain of x ≥ 0.

A. linear.

We know that linear function is in form , which is defined for all values of x, therefore, option A is not a correct choice.

B. Square

We know that a square function is in form , which is defined for all values of x, therefore, option B is not a correct choice.

C. Square root.

We know that a square root function is in form . We also know that a square root function is not defined for negative values of x, so a square root function is defined for all values of . Therefore, option C is the correct choice.

D. Cube

We know that a cube function is in form , which is defined for all values of x, therefore, option D is not a correct choice.
