Decide whether the relation defines a function.
-$$4 x - 10 y > - 10$$
A) Function
B) Not a function

Quizplus · Accepted Answer

A relation defines a function if for every input (x-value), there is exactly one output (y-value). The given relation $4x - 10y > -10$ is an inequality representing a region in the xy-plane, not a function, because for each x-value, there can be many y-values that satisfy the inequality.
