Question

Please help! Thank you!

Answer 1

103. Does not represent a function and 104. Does represent a funtion

Answer 2

*103 does not represent a function. You can check this by drawing a straight line down the graph, if the line touches more than one point it is not a function.

*104 does represent a function since the "line" would only touch one point in the graph.

Hope this helped
