Final answer:
For the provided expression 2x - 6, there are no restricted values of x unless it is part of an unrevealed denominator, in which case x ≠ 3 would be the restriction.
Step-by-step explanation:
To find the restricted values of x for the rational expression 2x - 6, we first need to identify any values that would make the expression undefined. In other words, we need to find values of x that would make the denominator equal to zero since division by zero is undefined. However, since there is no denominator given in this expression, it implies that there are no restrictions for values of x, assuming this is indeed the full expression and there's no denominator we are not seeing. So in this case, the answer would be A) No Restrictions. If we are dealing with a situation where the expression is part of a denominator (not shown in this question), we would then set that expression equal to zero and solve for x to find the restrictions.
