Statement 1 is false.
While it is true that some of the y-values have more than one corresponding x-value, this does not make the relation not a function. It would not be a function if some of the x-values had more than one corresponding y-values.
Statement 2 is true.
The domain of a function is all the x-values it encompasses. This function starts at 3 and ends at 8.
Statement 3 is false.
The range of a function is all the y-values it encompasses. This includes all the y-coordinates, but it does not express the range properly. The range is [6, 10].
Hope this helps!!
