Multiple Choice

Which of the following is NOT a value listed for a?

Explanation:
This question tests whether you know how to check which values actually satisfy the condition that defines a. To know which numbers could be a, you test each candidate against the relationship that a must meet—usually by substituting into the equation or applying its constraints. The value that does not satisfy the defining condition is not a valid value for a, even if it looks plausible at first glance. In this case, the value two does not meet the condition that defines a, while the other listed numbers do satisfy it. So two is not a possible value for a.
