- Ak = 3 or k = -3
- Bk = 9 only
- Ck = 3 only
- Dk = 0 only
Step-by-Step Solution
The -coordinate is already 0, so A is on the -axis. To be the origin, the abscissa must be 0: or .
Answer: A) k = 3 or k = -3
A point A, 0) lies on the -axis (which is automatic) and is exactly the origin. Find all possible values of .
