Answer:
D.

Explanation:
We have been given a quotient
. We are asked to find an inequality that represents all values of x for which the quotient below is defined.
We can rewrite our given expression as:
We know that a square root expression is defined for all values of x greater than or equal to 0. We also know that a fraction is defined when its denominator is greater than 0.
So our fraction will be defined for all values of x greater than 0.

Upon dividing both sides of our inequality by 4, we will get:


Therefore, the inequality
represents all values of x for which the given quotient is defined and option D is the correct choice.
