Answer:
(3,7), (3,8), (3,9), (3,10) is not a function.
Step-by-step explanation:
A function is defined as a relation in which each input value has only a single output value.
This means that for each value there should be only one
value. If this criteria is not fulfilled then the relation cannot be called a function.
For the given set of points, we notice that for , which shows there are many y-values o for a single x-value. This means there are many outputs for a single input. This disqualifies it to be a function.
Thus, (3,7), (3,8), (3,9), (3,10) is not a function.
