Does this table represent a function, why or why not

For this case we have that a function is defined as the relationship that exists between two sets. In said relation, each element of the starting set (represented by the variable "x"), corresponds to a single element of the arrival set (represented by the variable "y").

Thus, we observe in the table that each value of the starting set corresponds to a single element of the arrival set. Then we have a function.

Option B

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
