the table is a function because the domain values are
different.
the table is not a function because of the same domain and
different range values.
the table is not a function because of the same range and
different domain values.
the table is a function because the range values are the
same.

The table is not a function because of the same range and different domain values.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
