Determine whether the relation is a function. { (10, 2), (- 10, 2), (6, 4), ( 5, 3), (- 6, 7) }

It is a function. None of the x values repeat

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
