Question

is (3,7), (3,8), (3,9), (3,10) a function

Answer 1

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 $x$ value there should be only one $y$  

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 $x=3$, $y=7,8,9,10$ 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.
