The set of relations above is a function., it is called a many-to-one relation whereas the domain is paired once to a range.
\n" ); document.write( "Domain D {1,2,3,4}
\n" ); document.write( "Range R {7}\r
\n" ); document.write( "\n" ); document.write( "note that the sets of relation can be called function sets if the domain is paired only once to a range. It doesn't matter if the range is paired two or more times in domain just make sure that the domain is not paired two or more times in range.\r
\n" ); document.write( "\n" ); document.write( "The table of values
\n" ); document.write( "X|1|2|3|4|
\n" ); document.write( "--------------
\n" ); document.write( "Y|7|7|7|7|\r
\n" ); document.write( "\n" ); document.write( "base on this table, the value of x is not repeated and y is repeated, so it is still a function.\r
\n" ); document.write( "\n" ); document.write( "You can graph that in a cartesian plane and using the vertical line test (VLT), you can test whether the set of relation is a function or not., if u draw a vertical lines in every points, then it only intersects one point, it is a fuction, if it intersects 2 or more points, then it's not a function.\r
