No it is not a function. As for x=3we have two outputs y=6andy=8. But a function can have one output for one input.

Step by step solution

01

Given information

We are given coordinates given as{(3,6),(1,3),(2,5),(3,8)}

02

Explanation

By definition of function we have A function is defined as a relation between a set of inputs having one output each

but in this case for x=3we have two outputsy=6andy=8. Hence the given relation is not a function.
